Function

Once a Natural Command Processor has been created using the Natural utility SYSNCP, it can be invoked from a Natural program using the PROCESS COMMAND statement.

For details on how to create a Natural Command Processor, refer to the SYSNCP Utility documentation.

DDM Used for Command Processing

Important:
The word COMMAND in the PROCESS COMMAND statement is in fact the name of a view. The name of the view that is used need not necessarily be COMMAND; however, we recommend the use of COMMAND because there exists a DDM (data definition module) that is also called COMMAND. This DDM must be referenced within the DEFINE DATA statement, for example COMMAND VIEW OF COMMAND.

The DDM COMMAND has been created specifically for use in conjunction with the PROCESS COMMAND statement:

DB:    1 File:    1 - COMMAND                          Default Sequence: ?
  
  TYL  DB  NAME                             F LENG  S D   REMARKS
  ---  --  -------------------------------- - ----  - -  ------------------------
    1  AA  PROCESSOR-NAME                   A    8  N D DE    USING
  M 1  AB  COMMAND-LINE                     A   80  N D MU/DE USING
    1  AF  GETSET-FIELD-NAME                A   32  N D DE    USING
    1  BA  NATURAL-ERROR                    N  4.0  N         GIVING
    1  BB  RETURN-CODE                      A    4  N         GIVING
  M 1  BC  RESULT-FIELD                     A   80  N   MU    GIVING
    1  BD  GETSET-FIELD-VALUE               A   32  N D       USING; GIVING
  ***** DDM OUTPUT TERMINATED ******

The fields contained in the DDM correspond to the fields used in the PROCESS COMMAND statement. They are explained in Syntax Element Description.

Note:
To avoid possible compilation or runtime errors, make sure that the DDM named COMMAND is cataloged as type C (field DDM Type on the SYSDDM Menu) before you use it. (If you re-catalog the DDM, any DBID/FNR specification in the SYSDDM utility will be ignored.)

Security Considerations

With Natural Security, it is possible to restrict the usage of certain keywords and/or functions which are defined in a Command Processor. Keywords and/or functions can be allowed/disallowed for a specific user or group of users. See the Natural Security documentation for details.

Syntax Element Description:

Syntax Element	Description
`CHECK`	CHECK Action: `CHECK` is used as a precautionary measure to determine if a command is executable with the statement `PROCESS COMMAND EXEC`. It works as follows: for the given Command Processor name, a runtime check is performed in two steps: It is checked whether the Command Processor exists in the current library or one of its steplibs; The content of the command line `COMMAND-LINE (1)` is analyzed to determine whether it is acceptable. In addition, the runtime action definitions `R`, `M` and `1-9` are written into `RESULT-FIELD (1:9)`. If the field `NATURAL-ERROR` is specified in the view or in the `GIVING` option, it returns the error code. If this field is not available and the command analysis fails, a Natural system error occurs. Note: No `CHECK` is required if you want to perform an `EXEC` action. The `CHECK` is included in an `EXEC` operation.
`EXEC`	EXEC Action: `EXEC` works exactly the same as `CHECK` with the addition that the runtime actions are executed as specified in the runtime action editor. Only `COMMAND-LINE (1)` is needed. You can use up to 9 occurrences of `RESULT-FIELD` (however, for optimum performance, you should not use more occurrences than you really need). Note: `EXEC` is the only action which can be used to leave the currently active program. This is the case when the runtime action definition contains a `FETCH` or `STOP` statement. See also Example 1 - PROCESS COMMAND ACTION EXEC.
`TEXT`	TEXT Action: `TEXT` delivers general information about the Command Processor and text associated with a keyword or function. This text is the same as that entered in the keyword editor or action editor of the `SYSNCP` utility during Command Processor definition. For further information, see the following sections under Input Values for TEXT Actions: TEXT for General Information TEXT for Keyword Information TEXT for Function Information Note: To access texts for keywords and functions, you must have specified `Y` in the field `Catalog user texts` on the Processor Header Maintenance 3 screen of the `SYSNCP` utility, see the section Miscellaneous Options - Header 3.
`HELP`	HELP Action: `HELP` returns a list of all valid keywords, synonyms, and functions for the purpose of, for example, the creation of online help windows. This list is contained in the field(s) of `RESULT-FIELD`. The type of help returned is dependent on the content of the command lines. `COMMAND-LINE (1)` must contain the search criteria. `COMMAND-LINE (2)`, if specified, must contain the start value or a search value. `COMMAND-LINE (3)`, if specified, must contain a start value. For further information, see the following sections under Input Values for HELP Actions: HELP for Keywords HELP for Synonyms HELP for Global Functions HELP for Local Functions HELP for IKN HELP for IFN Note: For optimum performance, the number of occurrences of the field `RESULT-FIELD` should not exceed the number of lines to be displayed on the screen. At least one occurrence must be used.
`GET`	GET Action: `GET` reads internal Command Processor information and current Command Processor settings from the dynamically allocated `NCPWORK` buffer.
`SET`	SET Action: `SET` modifies internal Command Processor settings in the `NCPWORK` buffer.
`CLOSE`	CLOSE Action: `CLOSE` terminates the use of the Command Processor and releases the Command Processor buffer. When the Command Processor is used during a session and is not released with `CLOSE`, then there exists a buffer named `NCPWORK` in your thread. The parameters of this buffer may be evaluated by using the system command `BUS`. The runtime part of the Command Processor requires this buffer; it can be released using the statement `PROCESS COMMAND ACTION CLOSE`. If any `PROCESS COMMAND` statement follows this statement, then the Command Processor buffer will be opened again. See also Example 2 - PROCESS COMMAND ACTION CLOSE.
`GIVING`	GIVING Option: This option is only required in reporting mode and if no `VIEW OF COMMAND` has been defined in the `DEFINE DATA` statement. The `GIVING` option is not available in structured mode, because there exists an implicit `GIVING` option made up of all fields specified in the `DEFINE DATA` statement, which are usually referenced in the `GIVING` option for the reporting mode. This means that in structured mode all field defined in the `GIVING` option must be defined in the `DEFINE DATA` statement. Note: Specified in the `GIVING` option are fields to be filled by the Command Processor as a result of the processing of any action.
`PROCESSOR-NAME`	The name of the Command Processor to be used for processing. The Command Processor specified must be cataloged.
`COMMAND-LINE`	The command line to be processed by a `CHECK` or an `EXEC` action, or the keyword/command for which user text or help text is to be returned to the program by a `TEXT` or `HELP` action. Note that this field can contain more than one occurrence.
`RESULT-FIELD`	Contains information resulting from the use of options that can be specified within a runtime action defined for a Command Processor function (see Runtime Actions in the Natural `SYSNCP` utility). Note that this field can contain more than one occurrence.
`RETURN-CODE`	The return code of an operation resulting from an `EXEC` or a `CHECK` action as specified within a Runtime Actions definition (see the Natural `SYSNCP` utility).
`NATURAL-ERROR`	The Natural error returned for a `PROCESS COMMAND` action. We recommend that you use this field in the `DEFINE DATA` statement as it returns the Natural error code for the Command Processor. When the field is absent, Natural runtime error processing is triggered if an error occurs.
`GETSET-FIELD-NAME`	The name of the constant or variable that is read when a `GET` action is performed or that is written with a `SET` action. For a list of possible values for `GETSET-FIELD-NAME`, see Input Values for GETSET-FIELD-NAME.
`GETSET-FIELD-VALUE`	The value of the constant or variable specified in the field `GETSET-FIELD-NAME` which is read when a `GET` action is performed or which written with a `SET` action.

This section covers the following topics:
