Predict: Each object in Predict can have an abstract providing short comments on the object. An abstract can have up to 16 lines of up to 30 characters. In earlier versions of Predict, an abstract was referred to as "Comments" or "Short comments". The name was changed for reasons of compatibility with other Software AG products.
Activation policy is an attribute of a NaturalX class that is to be registered as a DCOM class. It defines whether the class may share a Natural session with other classes.
NaturalX combines the different options supported by DCOM in the form of the following three activation policies:
ExternalMultiple
ExternalSingle
InternalMultiple
The activation policy of a class can be set as part of the
REGISTER command, in the DEFINE
CLASS statement or with the profile parameter
ACTPOLICY.
Predict: If parameter values needed to execute a function are missing, active help is given in the form of a selection window containing all possible values. This applies to all input fields marked with an asterisk.
Predict: See XRef Data.
Predict: Active retrieval functions retrieve information from XRef data and from Predict documentation objects. Comparison of documentation and implementation of a system is possible.
Windows: Standardized Microsoft interface to external programming components, for example, business logic or calculations. ActiveX components have no user interface.
Windows: A standardized programming component with a user interface e.g. radio buttons or list boxes, which can be used in Natural dialogs.

The number of bits (24 or 31) of a virtual address used during program execution.
In the Windows system registry, each application is represented by an AppID. The AppID is a globally unique ID, which can be found under the registry key HKEY_CLASSES_ROOT\AppID. DCOM uses the AppID to group classes to applications. Also, for example, security settings are defined on the basis of the AppID. Natural creates for each NaturalX server ID one AppID in the registry.
For further information, see the section Server ID.
A logical view of a collection of interconnected programming elements. Together, they form a functional unit which covers the business logic for a particular business problem. An application consists of a set of libraries and their Natural objects and/or sub-applications (business objects). The contents of a library (Natural objects, resources, etc.) can belong to different applications. Information concerning an application (the application description) is held in the development server file which is accessible from all platforms.
There are two types of application:
Base Applications
Base applications consist of one application on one platform,
for example, a theater ticket booking system.
Compound Applications
Compound applications consist of multiple base applications,
for example, a theater administration application combining applications for
booking tickets, billing customers and mailing customers with performance
information. The base applications can be on multiple platforms.
A list of all the elements belonging to an application, stored in the development server file. The database file (at present FDIC on the mainframe) in which application information is physically stored. See Development Server File.
The code which handles access to the application description.
A programming object that allows the user to access and possibly
modify data or to use services that are specific to Natural, a subcomponent or
a subproduct. The purpose of an application programming interface is to
retrieve or modify information or use services that are not accessible by
Natural statements. Application programming interfaces can be invoked from
Natural objects using CALLNAT or CALL
statements, depending on the respective application interface.
Windows: A tool for defining what belongs to a certain application. Dialog boxes guide the user through creating an application description for an existing application.
Windows: Used to view a visual representation of an application in a tree view. The application workspace shows all elements belonging to the current application.

propagating Natural buffer pool objects;
writing system management facility (SMF) records;
holding Natural session information in the Session Information Pool (SIP).
ASM provides functions via PC routines and runs in its own address space.
Predict: Predict documentation objects can be linked using associations. Different types of associations are used to link objects of different types. Associations are unidirectional (child and parent association).
Additional association types can be defined by the data dictionary administrator using the Metadata Administration functions of Predict.
An asynchronous Natural session is an "online" session (i.e. running under a TP monitor) which is not associated with any terminal and therefore cannot interact with a terminal user.
Predict: The wildcard character "*" (an asterisk) can be used to specify input parameters that address groups of values. For example, if "datab*" is entered as an ID, all IDs starting with the characters "datab" are addressed.
Predict: Predict documentation objects have attributes describing the object.
Windows: A program which can be used via an automation interface. For further information, see your Microsoft documentation.
See Application.
IMS TM: Programs running asynchronously in batch mode under control of IMS TM.

A BLOB is a "Binary Large Object", in other words, a very large variable.
A Natural statement issued to cancel a database transaction and
restore the condition of the data before starting the transaction. See also
Transaction
and END TRANSACTION (ET).
In Natural, this is a storage area used by the Natural nucleus to execute Natural objects (see also Object Types). When a Natural object is requested for execution, it is read from the system file and placed in the buffer pool, where it can be used by several users simultaneously.
A buffer area used to temporarily store copies of data most recently retrieved from the main memory. This avoids unnecessary access to system files and external databases/file systems thus reducing CPU time consumption and speeding up response time.
In Natural, the term "catalog" refers
to the Natural system command CATALOG. This command
compiles (catalogs) source code and stores the generated object code as a
cataloged object in a Natural system file.
In Natural, a cataloged object is the executable (compiled) form of a Natural object. A cataloged object is stored as an object module in a Natural system file.
Mainframe: An object that is cataloged on the mainframe is executable on the mainframe only. On the mainframe, it is possible to optimize a cataloged object using the Natural Optimizer Compiler.
Windows and UNIX: As of Natural Version 5.1, cataloged objects are portable across all Windows and UNIX supported by Natural (not on the mainframe). It is also possible to specify the endian mode for a cataloged object if required.
Synonyms: The term "GP" or "generated program" is also used synonymously to cataloged object. In Predict Application Control, the term "loadable" is used.
See also Source Object, Object and Object Types.
z/OS: Hardware component used to control and coordinate access to data shared by the operating systems participating in a Parallel Sysplex environment. The CF is used by the Natural Authorized Services Manager (ASM) and the Natural Roll Server to communicate in a Parallel Sysplex environment.
Used by Natural Web Interface to provide Internet services in Natural.
In Natural, the term "check" refers to
the Natural system command CHECK. This command
checks whether the syntax of the source code contains any
errors.
Predict: Associations are used to document how Predict objects are related to other Predict objects. An association is established by linking objects to an object either as child or parent. For example, a field is the child of a file; a file is the child of a database.
z/OS: IBM's online transaction processing system.
A set of interconnected CICS regions acting as resource managers, and combining to provide a set of coherent services for a customer's business needs.*
Natural classes encapsulate data structures (objects) with corresponding functionality (methods). See also NaturalX Class.
The internal structure of the objects of a class object is defined with a data area (object data area). The methods of a class are implemented as subprograms.
Windows: Supports the definition and implementation of NaturalX and DCOM component classes as Natural classes. A Natural class can be composed of various components: Natural objects (for example, an object data area) or objects which exist only in the class source (for example, interface components). The Class Builder represents each component of the class in the form of a node. By selecting these nodes, the class and its components can be managed in a context-sensitive manner. See Class Builder in the Editors documentation.
If a NaturalX class is to be registered as a
DCOM class, a globally unique ID (GUID)
must be defined for the class, to make sure it can be unambiguously identified
in a network. In Natural, a GUID is assigned to a class in the ID clause of the
DEFINE CLASS statement. A GUID is represented by an
alphanumeric constant which can be generated in the data area editor. The
Natural Studio Class Builder automatically assigns a new GUID to each new
class.
The name defined in the class-name
operand in the DEFINE CLASS statement. This name is
used in the CREATE OBJECT statement to create
objects of that class. See also
DEFINE
CLASS in the Statements
documentation.

The global configuration file contains DBMS assignments,
dictionary server assignments, assignments of printer profiles, and system file
assignments.
For further information, see Overview of Configuration File Parameters in the Configuration Utility documentation.
Predict: First phase of the Coordinator Check Cycle. With Predict Version 3.3 and above, all objects have an Internal ID. Conflict Management means the resolution of conflicts resulting from this Internal ID. A possible conflict could be two objects with the same object ID but different Internal IDs.
Conflicts resulting from the Internal ID must be resolved in the Coordinator FDIC before data can be loaded or imported to the Main FDIC.

Predict: A connection between an external and a documentation object is established when either the external object has been generated from the documentation object or the documentation object has been incorporated from the external object. Most connected external and documentation objects can be disconnected explicitly.
The connection is realized on the Predict side with the implementation pointer, an attribute of documentation objects.
Predict: Third phase of the Coordinator Check Cycle. Objects to be transferred are checked for logical consistency, for example that a file number only occurs once within a database. The same checks are performed as in Maintenance functions.
Natural supports the following types of constants:
Numeric Constants
Alphanumeric Constants
Date and Time Constants
Hexadecimal Constants
Logical Constants
Floating Point Constants
Attribute Constants
Handle Constants
See User-Defined Constants in the Programming Guide.
Predict: When objects are loaded or imported using the Predict Coordinator, they have to pass a check cycle consisting of the following phases: Conflict Management, Security and Consistency Check. Conflicts in either of the phases must be resolved on the Main or Coordinator FDIC before the Load or Import function can continue.
Predict: The Coordinator FDIC is a Predict file which is used to store data temporarily when using the Coordinator functions Load or Import. Conflicts must be resolved on this Coordinator FDIC before the load/import operation can be continued. The data on the Coordinator FDIC is deleted after the function has been successfully executed.
Predict: Fields that are copied from fields in standard files or master files are called coupled fields.
Predict: A listing produced by Predict function X in the Retrieval and Active Retrieval menu showing all objects to which a given object is linked by an association.

Predict: Some retrieval types (for example: files with children) report on both the attributes of objects that meet the specified selection criteria and the attributes of objects that are related to these objects. When specifying output options, the objects that meet the specified selection criteria are called the current objects.
Predict: Network and virtual machine objects document the hardware and operating system environment of an information processing system. Predict stores a current virtual machine and a current network which is then used
as default parent for databases and virtual machine objects
as the target environment for Generate/ Incorporate/Compare functions and some AOS functions called from the Predict Special functions menu.
Current virtual machine and current network are specified in the Predict Defaults.
Predict: Predict documentation objects of type database document a collection of physical and/or logical files. The way files are collected to form an object of type database depends on the type of database documented.

BACKOUT TRANSACTION (BT).
Windows: Event-driven programming allows an application to be driven by input received through the graphical user interface. Thus, the order in which code executes depends on which events occur, which in turn depends on what the user does. See Introduction to Event-Driven Programming in the Programming Guide.
Predict: The Coordinator function Export is used to export Predict data in a form which allows data exchange with other systems. You can also export text from attributes of a Predict object (for example extended description or subquery of a File), or from the output of a display-oriented Predict function (for example Retrieval or Active Retrieval), to an external target (for example Natural, a Con-nect document or a PC ASCII file).
A NaturalX class can be a local, an internal or an external class.
This depends on the way the class was registered. An external class is a class

by using Adabas descriptors. You can either couple files physically (hard
coupling) using ISN lists, or logically (soft coupling) by evaluating the
search result (FIND statement) dynamically at
runtime.
Predict: A Predict object of type File Relation documents a logical or physical relationship between two Files which is established using Fields in the Files.

Predict: With one exception, Predict objects are uniquely identified by two attributes: Object type and ID. Objects of different types can therefore have the same ID.
Field objects are uniquely identified by three attributes: Object type, ID of the File to which they belong, and ID of the field itself. Field objects in different Files can therefore have the same ID.
Abbreviation for "Internet Information Services" (Microsoft).
Predict: The Coordinator function Import is used to import data from a transfer medium to a Predict environment. You can also import text from various external sources, such as Natural, a PC ASCII file or a Con-nect document, to a text attribute of a Predict object, for example the extended description of any Predict object, or the subquery of a File.
z/OS: Component of IMS: the IMS database management system from IBM that provides access to DL/I databases. See also Information Management System.
Obsolete. Replaced by IMS TM.
z/OS: Component of IMS: the IMS online transaction processing system from IBM. See also Information Management System.
Predict: Predict data dictionary objects can be created by incorporating external objects (for example, an existing Natural data definition module or Adabas field definition table).
Any of several system environments available with Database Manager (IMS DB) and Transaction Manager (IMS TM), capable of managing complex databases and terminal networks.*
Natural utility used to load or scan Natural modules or DDMs from Software AG data sets (for example Natural INPL tapes) from work file 1. In addition, it provides a Natural Security Recover function that enables you to force an initialization of the Natural Security environment.
In the object-oriented programming model, data structures and functions (so-called "methods") are packaged together in objects. Each object belongs to a class, which describes the internal structure of the object and its interfaces, properties and methods. If an object belongs to a certain class, it is also called an instance of that class.
Interfaces are used by classes to provide clients with services. An interface is a collection of methods and properties. A client accesses these services by creating an object of the class and using the methods and properties of its interfaces.
You define an interface as follows:
Define the INTERFACE clause to specify an
interface name.
Define the properties of the interface with
PROPERTY definitions.
Define the methods of the interface with METHOD
definitions.
If a NaturalX class is to be registered as a
DCOM class, a globally unique ID (GUID)
must be defined for each of its interfaces, to make sure the interfaces can be
unambiguously identified in a network. The GUID is assigned to an interface in
the ID clause of the INTERFACE
statement. In Natural, a GUID is represented by an alphanumeric constant, which
can be generated in the data area editor. The Natural Studio Class Builder
automatically assigns a new GUID to each new interface.
Interface inheritance means giving different classes the same interfaces, but implementing the interfaces differently in the different classes. This makes it possible to write client programs that only rely on these interfaces and are able to work with any class that has these interfaces.
A Natural copycode module which defines interfaces. The interface module can be used in a class to define the contained interfaces. The class can overwrite the method and property implementations, but all other settings of the interface are used as defined in the interface module.
A NaturalX class can be a local, an internal or an external class.
This depends on the way the class was registered. An internal class is a class
that has been registered as a DCOM class
with the REGISTER command option IM
(InternalMultiple). Objects of internal classes cannot be created by other
processes, but they can be accessed by other processes. This requires that the
object has been passed to the client process for example as return value of a
method.
For further information, see Local Class and External Class.
Predict: Each Predict object type is internally identified by an internal code. Internal codes are assigned by Predict and cannot be changed by the user.
Predict: As of Predict Version 3.3, all objects have an internal ID. This ID is allocated automatically when an object is added. It is unique worldwide and remains with the object throughout its entire life span.
An interface which is defined directly in the class, or an interface of an interface module, which is defined in the interface module.
An area that contains the most frequently used data and data relationships. It helps to minimize physical input/output activity, thus saving computer time.
Abbreviation for "input/output control block".
The procedure which initializes the loading of an operating system.
Used by Natural Web Interface to provide internet services in Natural.

For mainframe Natural, these parameters are included in the NTRPC macro (static definition) or are defined with the profile parameter RPC (dynamic definition).
Mainframe: See Parameter Module.
Windows and UNIX: By default, the parameter specifications in the parameter file NATPARM.SAG are used to determine the characteristics of your Natural environment. Initially the NATPARM parameter file contains the default values supplied by Software AG. If you want to use Natural with parameter values other than the system defaults, you can modify the default parameter file NATPARM.SAG and/or create your own parameter files using the Natural Configuration Utility. All parameter files must have names of 8 characters and the extension .SAG.

dynamic parameters. A profile in this context means a string of profile
parameters stored under a profile name.
A Natural profile parameter defines a characteristic of the Natural environment.
The value for a profile parameter is taken from the following three sources:
Runtime assignment of a session parameter which is specified
in the Natural SET GLOBALS statement or the
GLOBALS system command (highest priority).
Dynamic assignment which is valid for the current Natural session. This is made by specifying an individual parameter when starting Natural.
Static assignment which is specified in the Natural parameter module/parameter file (lowest priority). On the mainframe, this is the parameter module linked to the Natural nucleus. Under Windows and UNIX, this is the parameter file NATPARM.SAG.
For further information, see the platform-specific Natural Operations documentation.
Natural profile parameters are set at different hierarchically organized levels as illustrated in the table below (priority from high to low).
| During session (highest priority) |
Development environment settings. Program/statement level settings. Session parameter settings. Natural Security definitions. |
|---|---|
| Dynamic during session start |

Predict: A field in a standard file. Standard files and fields enforce standard use of fields in different files.
Predict: A standard file documents the overall layout of all data processed within an organization (data definitions and/or company standards). Fields in standard files do not refer to an implemented data structure directly: field definitions in a standard file are rippled to master files of different types.
See Rippling.
The *STARTUP system variable contains
the name of the program used to start a session.
If you map a Natural Development Server environment
(*SERVER-TYPE) from NaturalONE and use the startup
program supplied by *STARTUP, make sure that this
program does not perform screen I/O and terminates properly in its containing
library.
See also the description of the *STARTUP system variable.
See the Statements documentation.
Mainframe: Assigned by profile parameters specified in the Natural parameter module which is created during the installation.
Windows and UNIX: The parameter settings specified in NATPARM.SAG.
A steplib is a Natural user library or system library that is concatenated with the current user or system library. A steplib can be used as a single storage location for multiple objects that are shared by different applications. This avoids redundant storage of identical objects and helps to organize applications. In addition, if Natural Security is installed, a steplib can be used to restrict access to particular objects.
Predict: Predict objects of type storagespace document DB2 storagegroups.
In Natural, the term "stow" refers to
the Natural system command STOW. This command saves
and, at the same time, catalogs (compiles) source code as a source object and
as a cataloged object in a Natural system file. Both objects then have the same
time stamps.
A socket program that establishes the link between the local application program and the broker. See also RPC Stub.
Predict: Object types can have subtypes. The object type file, for example, has the subtypes Adabas file, Adabas userview, DB2 table, DB2 view, etc. The subtypes of the object type file, for example, are also called file types.
Software AG's end-user tool for extracting and processing data from mainframe or PC files. It offers menu-driven query specification, interactive report layout specification, and flexible customization of end-user profiles.
A request that serves as the interface into operating system functions, such as allocating storage. The SVC protects the operating system from inappropriate user entry. All operating system requests must be handled by SVCs.*
CICS and IMS TM: A logical point in execution of an application program where the changes made to the databases by the program are consistent and complete and can be committed to the database. The output, which has been held up to that point, is sent to its destination(s), the input is removed from the message queues, and the database updates are made available other applications.*
Mainframe: Used for creating and maintaining parameter
profiles. You can specify a string of profile parameters once, store this
string under a profile name, and then invoke Natural with the dynamic parameter
PROFILE=profile-name. The
string of parameters stored under that profile name is passed to Natural as
dynamic parameters.
Utility for configuring the services, and server connections for each Natural client using remote procedure calls. See SYSRPC Utility in the Tools and Utilities documentation.
Predict: Predict objects of type system document a collection of programs forming an application or a part of an application.
Natural system commands perform functions you need to create, maintain or execute Natural objects. In addition, Natural system commands are used to monitor and administer your Natural environment.
The Natural system files (FNAT, FUSER) contain information, data programs, modules, etc., which are required for the Natural system to function. Products like Predict, Natural Security, Natural Advanced Facilities and Natural for VSAM require their own system files (FDIC, FSEC, FSPOOL, FDICX).
Preprogrammed functions offered by Natural. See the System Functions documentation.
Natural-internal library created in FNAT at installation, not available for customer-modification. All Natural system library names start with the letters "SYS" (with some exceptions on the mainframe).

Predict: Programs that are not available as source code are documented with Predict objects of type Program with subtype E (external object) and language Z (system program). Whenever a system program is created in Predict, XRef data is written for it.
System variables are used to display system information. They may be referenced at any point within a Natural program. See the System Variables documentation.
Abbreviation for "transaction code".
Mainframe: In a multiprogramming or multiprocessing environment, one or more sequences of instructions treated by a control program as an element of work to be accomplished by a computer.*
Windows and UNIX: See Process.
z/OS: A control block allocated by the operating system which contains all information on tasks relevant for the system.
CICS: Data temporarily stored in a facility. A transient object is automatically deleted when it is no longer used.
You can define another special character as control character
using the session parameter CF.
See the
Terminal
Commands documentation.
To structure the output of large integer values, it is common practice to insert separators between every three digits of an integer to separate groups of thousands. This separator is called a "thousands separator".
In Natural, a "dynamic thousands separator" is a specific character in the edit mask to indicate the position where the thousands separators are inserted at runtime.
The "thousands separator character" is the character to be used as the thousands separator at runtime.
Mainframe: A storage space which contains all the data for a particular Natural session.
Windows and UNIX: The basic (memory) entity within an application to which the operating system allocates CPU time. Threads allow parallel computing in single and multiple processors. They execute independently from each other.
Is the successor of SSL.
z/OS: A control program for the administration and management of online transaction processing (OLTP) applications. TP monitor technology complements the operating system and serves as an intermediate tier encapsulating access to resources. The user or application programmer is thus shielded from technical details on the operating system level, for example concerning database access.
Predict: When data is transferred using the Predict Coordinator, the transfer medium used can be a PC work file, a Natural work file or a file in a database. For the Coordinator functions Unload and Export, the transfer medium is the target environment; for the Coordinator functions Load and Import, the transfer medium is the source environment.
Input of application data submitted by a single user that initiates a sequence of information exchange and execution of operational steps (input - data processing - output). A transaction code is needed to initiate the process.
Natural performs database updating operations based on
transactions (database transactions), which means that all database update
requests are processed in logical transaction units. A logical transaction is
the smallest unit of work (as defined by user) which must be performed in its
entirety to ensure that the information contained in the database is logically
consistent. The statements END TRANSACTION
(ET) and BACKOUT TRANSACTION
(BT) cause the database to
unlock all records since the begin of the transaction.

Database
Access in the Programming
Guide.
Predict: Database that contains the ADASTAR translation table that is used to determine the physical file behind any logical file number when using Adabas Star.
Visual representation of element hierarchy.
When a NaturalX class is registered as a DCOM class, a type library is generated for the class and connected to the class by a Windows system registry entry. Clients can use the type information contained in the type library to check the descriptions of the interfaces, methods and properties of the class either at compile time or at runtime.

Predict: Predict objects of type user document persons using a system. A logical connection between users and documentation objects is established by means of owners. See Object Types.
Abbreviation for "Uniform Resource Locator", a subtype of Uniform Resource Identifier (URI). In popular usage and in some technical publications it is a synonym for URI.
A field which you define yourself in a program. It is used to store values or intermediate results obtained at some point in program processing for additional processing or display.
You define a user-defined variable by specifying its name and its
format/length in the DEFINE DATA statement.
See the section
User-Defined
Variables in the Programming
Guide.
A user exit is a point in Natural, a subcomponent or a subproduct where control is passed to a user exit routine.
A user exit routine assumes control at a defined user exit to manipulate data or make decisions. Usually, a sample user exit is delivered in source form. The instructions contained in the user exit have to be written or adjusted by the user. Most user exit routines take advantage of the Natural language; a small subset has to be written in Assembler language on mainframe systems and C on non-mainframe systems.
Predict: Userviews are logical views of master files defined for use in the data declaration sections of programs. The number and sequence of fields in a userview can differ from the master files and - within certain compatibility rules - certain attributes of fields in userviews can differ from the corresponding values at the physical/logical level.
See System Variable and User-Defined Variable.
Predict: A Predict object of type verification documents the rules for the validation of field values. Natural processing rules can be generated from Predict objects of type verification.
According to the Software AG Maintenance Policy, the version (or release) of a Software AG product is defined as follows:
The first digit of the version indicates a major release with significant new features and functionality and, possibly, major architecture changes.
The second digit of the version indicates a minor release with some new features and functionality and fixes.
The third digit of the version indicates a Service Pack which is an accumulation of fixes delivered as a planned release. It can be denoted by "SP" in the version numbering.
The fourth digit of the version indicates a specific fix that can be cumulative.
In the product documentation, the current version is often represented by a placeholder such as vrs, v.r.s, vr, v, nnn or nn, for example, in data set or module names.
For further information on the Software AG Maintenance Policy, you can view the relevant section on Software AG's Empower website at https://empower.softwareag.com.
Predict: See Userview.
Predict: Together with objects of type Network, Predict objects of type Virtual Machine document the hardware and operating system environment of a data processing system.
A virtual data processing system that appears to be at the exclusive disposal of a particular user, but whose functions are accomplished by sharing the resources of a real data processing system.*
An IBM access method to maintain records of different data set organizations: key-sequenced data sets (KSDS), entry-sequenced data sets (ESDS) or relative-record data sets (RRDS).
An application programming interface (API) for communicating with Systems Network Architecture (SNA) telecommunication devices and their users.
An optional user-coded service that allows a message to be written to the system console operator informing the operator of errors and unusual system conditions that may need to be corrected.*
Describes the structure of the data that is saved in the target file. For example, the work file format ENTIRE CONNECTION writes two files: .NCD and .NCF.
For more information, see Work File Formats in the Operations documentation.
A file that is available to Natural, that writes a certain work file format. For example, there are two different work files types that save data in Entire Connection format. These file types are ENTIRE CONNECTION and TRANSFER.
For more information, see the
profile parameter WORK.
X-arrays, or eXtensible Arrays, are arrays of which one can alter the number of occurrences at runtime. This can help you manage memory more efficiently. For example, you can use a large number of array occurrences for a short time and then reduce memory when the application is no longer using the array. See X-Arrays in the Programming Guide for more information.
A component that provides functions to support cooperation between authorized programs running within a sysplex.*
Natural only uses XCF in connection with Parallel Sysplex.
Abbreviation for "Extensible Markup Language".
Windows: Enables developers to process XML documents within Natural. The toolkit includes a wizard which generates Natural source code and provides the following features:
Mapping Natural data definitions to DTDs;
Serialization;
Mapping DTDs to Natural data definitions;
Parsing an XML file and assigning its contents to a Natural data structure.
Predict: XRef data is stored in Predict for implemented objects; it is stored independent of documentation objects. Predict's active retrieval functions retrieve information from XRef data and from Predict documentation objects to determine
whether objects documented in the dictionary are not yet implemented,
whether implemented members are not yet documented or
whether documentation data differs from the implementation.
XRef data records for Natural objects are created by Natural when
a Natural object is cataloged. XRef data is generated when an object is
cataloged and the XREF parameter has been specified
accordingly.
Windows: The XRef Evaluation Plug-In is used to navigate
through cross-reference information created during
CAT or STOW commands in
the development server file. The information is displayed in a tree view in
Natural Studio. Both types of references - active and passive (i.e. referencing
and referenced) can be displayed. Navigating through the hierarchies of active
and passive references is possible within the tree-view. See the Single Point
of Development documentation.
