This section describes the utilities supplied with Natural Construct for use in the Administration subsystem. The following topics are covered:
This section describes the utilities supplied with Natural Construct for all supported platforms. To invoke a utility, enter its name at the Next prompt (Direct Command box for Unix).
Note:
When a description refers to “your print file” for mainframe users,
it refers to Print File 1. When a description refers to “your print file” for
Unix users, it refers to DEVICE LPT1.
This section explains how to transfer data across dissimilar platforms (for example, from Unix to mainframe).
Natural Construct’s import and export utilities read and write their data from and to work file 1. This is true for each of the following utilities:
| Utility | Described in |
|---|---|
| CSFLOAD
CSFUNLD |
Multiple Code Frame Import Utility |
| CSHLOAD
CSHUNLD |
Natural Construct Help Text |
| CSMLOAD
CSMUNLD |
Natural Construct Generation |
A work file written on one platform (such as Unix) can be read by another platform (such as mainframe) if the following conditions are met:
The work file must be an ASCII file. For example:
| Platform | How to save as an ASCII file |
|---|---|
| Mainframe | Define work file 1 as a PC file and activate PC Connection before running the utility. (PC Connection translates from EBCDIC to ASCII.) |
| Unix | Set the work file specification in your NATPARM to any extension other than “SAG”. |
When transferring the work file between platforms, select the appropriate translator. For example, the file transfer method you select to move a file from a PC to a Unix machine must translate the PC’s CR/LFs to CRs.
The CSFLOAD frame import utility imports selected code frames from work file 1 to the code frame file. A report of the imported code frames is written to your print file.
CSFLOAD accepts up to 100 frame names and replace options in the form:
Code frame . ________ Replace .... _
The following example shows the CSFLOAD window:
CSFLOAD ***** Natural Construct ***** CSFLOAD0
Nov 18 Multiple Code frame Import 1 of 1
Code frame . ________ Replace .... _

Note:
To replace the existing code frames with code frames with the same
names in work file 1, mark the Replace field. If you do not want to replace the
existing code frames, leave the Replace field blank.
| Values entered | Result |
|---|---|
| Code frame: * | Imports all code frames from work file 1. If a code frame with the same name exists in the code frame file, it is not replaced. |
| Code frame: MENU | Imports the “MENU” code frame from work file 1. If the “MENU” code frame exists in the code frame file, it is not replaced. |
| Code frame: MENU
Replace: X |
Imports the “MENU” code frame from work file 1. If the “MENU” code frame exists in the code frame file, it is replaced. |
| Code frame: FM* | Imports all code frames beginning with “FM” from work file 1. If a code frame with the same name exists in the code frame file, it is not replaced. |
| Code frame: . (period) | Terminates the CSFLOAD utility.
Note: |
The CSFUNLD frame export utility exports selected code frames from the code frame file to work file 1. A report of the exported code frames is written to your print file.
Note:
You can export a maximum of 1000 code frames at one time.
Enter each code frame name one name at a time. As you enter the names, they are automatically displayed on the panel.
For each exported code frame, you can specify whether to export its recursive (nested) code frames — if any exist. To export recursive code frames, mark the Include recursive code frames field. If you do not want to export recursive code frames, leave the field blank.
| Values entered | Result |
|---|---|
| * | Exports all code frames to work file 1. |
| MENU
X |
Exports the “MENU” code frame including any recursive (nested) code frames to work file 1. |
| FM* | Exports all code frames beginning with “FM” to work file 1. |
Enter a period (.) to terminate the input.
The CSFHCOPY frame hardcopy utility allows you to print a hardcopy list of your code frames, regardless of your teleprocessing monitor. All output is routed to your print file.
Enter each code frame name one name at a time. As you enter the names, they are automatically displayed on the panel.
| Values entered | Result |
|---|---|
| * | Routes all code frames to your print file. |
| MENU | Routes the “MENU” code frame to your print file. |
| FM* | Routes all code frames beginning with “FM” to your print file. |
Enter a period (.) to terminate the input.
This section describes utilities you can use to compare two Natural source modules and to compare a range of models in different libraries.
This program compares two Natural source modules. You can compare the contents of two saved modules or you can compare the contents of the module currently in the source buffer to the contents of a saved module.
Specify the library ID, module name, database ID, and file number for each module you want to compare. In addition, you can specify the following options:
ignore comment lines
ignore trailing comments
ignore leading spaces
provide summary only
When you invoke the CSGCMPS utility online, the following window is displayed:
Compare Criteria

This program compares a range of modules in one library to the same modules in another library.
Specify the library ID, database ID, file number, and range value for the modules you want to compare. In addition, you can specify the following options:
summary only
only report if different
ignore comment lines
ignore trailing comments
ignore leading spaces
only compare object types
When you invoke the CSGCMPL utility online, the following window is displayed:
Source Range Compare Facility
Library Database File Dominant
======== ======== ==== ========
Old library............... ________ __17 __29 X
New Library............... ________ __17 __29 _
Program range............. ________ thru ________
Summary only.............. _
Only report if different.. _
Ignore comment lines...... _
Ignore trailing comments.. _
Ignore leading spaces..... _
Only compare object types __________ (ACGHLMNPST) |
The Dominant column indicates the range of modules to be compared. Only modules that exist in the dominant library and in the other specified library are included in the compare results. Modules that only exist in the non-dominant library are not included.
The Only compare object types field limits the comparison to modules of a specified object type. Valid object types are:
| Object Type | Description |
|---|---|
| A | Parameter |
| C | Copycode |
| G | Global data area |
| H | Helproutine |
| L | Local data area |
| M | Map |
| N | Subprogram |
| P | Parameter data area |
| S | Subroutine |
| T | Text |
Batch mode is the most efficient method of comparing many modules. The following SYSIN shows an example of using this utility in batch:
LOGON CST421M CSGCMPL OLD-LIB,001,002,X,NEW-LIB,003,004, ,BEGIN,END,S,D,C,T,L,NPH FIN
where:
| OLD-LIB | Indicates the name of a library containing modules to be compared. |
| 001 | Indicates the database ID for OLD-LIB. |
| 002 | Indicates the system file number for OLD-LIB. |
| X | Indicates that the OLD-LIB is dominant (all modules in the dominant library are compared to matching modules in the other specified library). |
| NEW-LIB | Indicates the name of a library containing modules to be compared. |
| 003 | Indicates the database ID for NEW-LIB. |
| 004 | Indicates the system file number for NEW-LIB. |
| blank | If blank, indicates that OLD-LIB is dominant. If X, indicates that NEW-LIB is dominant. |
| BEGIN | Indicates the name of the first module in the range compared. |
| END | Indicates the name of the last module in the range compared. |
| S | Indicates a summary report (does not display detailed differences). This option displays the names of the modules and whether the module contents are the same in both libraries. |
| D | Indicates that only modules that are different are included on the output report. Modules that are identical in both libraries are not included. |
| C | Indicates that Natural comment lines (lines beginning with “*” or “/*”) are not compared. |
| T | Indicates that trailing comments (comments beginning with “/*”) are not compared. |
| L | Indicates that leading spaces are not compared (changes in alignment will not show up as differences). |
| NPH | Indicates the list of Natural object types compared within the specified range of modules. |
If you are developing applications in a language that does not support lower case Latin characters, use the supplied CVUPPERC utility to convert the Natural Construct components to upper case. This utility converts all Natural Construct-installed SYSERR message text and source code, as well as the contents of the Natural Construct system file, to upper case.
Notes:
Use the following SYSIN to invoke the CVUPPERC utility:
LOGON SYSCST CVUPPERC FIN
After converting the components to upper case, this utility issues a CATALL in the SYSCST library. To reflect the changes in your production environment, manually transfer all modules from the SYSCST library to the SYSLIBS library after the modules have been cataloged.
The utilities in this section generate cross-reference information for all subprograms referenced by a code frame or model. You can use these utilities either online (recommended) or in batch mode to determine which subprograms are invoked. If subprograms are missing, the utility will write a report to the screen.
To determine which subprograms are referenced by code frames, run the CVUVALF utility either online or in batch mode. The CVUVALF utility:
Verifies that all subprograms referenced by all code frames exist in the current library.
Generates CALLNAT statements for all subprograms used in the code frames. Online, these statements are generated into the program editor and you can view the parameter list.
To invoke the CVUVALF utility online:
Logon to the SYSCST library.
Run the CVUVALF program.
To invoke the CVUVALF utility in batch mode:
Use the following SYSIN:
LOGON SYSCST CVUVALF FIN
In this example, the utility provides a list of all subprograms that are referenced by all code frames and do not exist in the SYSCST library.
To determine which subprograms are referenced by models, run the CVUVALM utility either online or in batch mode. The CVUVALM utility:
Verifies that all subprograms referenced by all models exist in the current library.
Generates CALLNAT statements for all subprograms used in the models. Online, these statements are generated into the program editor and you can view the parameter list.
To invoke the CVUVALM utility online:
Logon to the SYSCST library.
Run the CVUVALM program.
To invoke the CVUVALM utility in batch mode:
Use the following SYSIN:
LOGON SYSCST CVUVALM FIN
In this example, the utility provides a list of all subprograms that are referenced by all models and do not exist in the SYSCST library.
