CHKSELOMT CHECK SELECT/OMIT TAACLTB |
The Check Select/Omit command allows select and/or omit lists to be
checked against a name value. The lists may contain generic names.
A *YES/*NO result field is returned to assist in your processing.
CHKSELOMT simplifies programming when performing select/omit
processing of names against lists.
For example, assume you have extracted a list of program names and
only want to process some of the names.
A typical series of commands would be:
DCL &RESULT *CHAR LEN(4)
.
CHKSELOMT NAME(&xxx) RESULT(&RESULT)
SELECT(ABC DEF GH*)
IF (&RESULT *EQ '*SEL') DO /* Selected */
.
ENDDO /* Selected */
Only the names ABC, DEF, or matching the generic name GHI would pass
back a result of *SEL.
Another typical command would be:
CHKSELOMT NAME(&xxx) RESULT(&RESULT)
SELECT(ABC DEF GH*) OMIT(AB* MMM OOO)
IF (&RESULT *EQ '*SEL') DO /* Selected */
.
ENDDO /* Selected */
IF (&RESULT *EQ '*OMT') DO /* Omitted */
.
ENDDO /* Omitted */
IF (&RESULT *EQ '*NON') DO /* Non-specified */
.
ENDDO /* Non-specified */
Because SELECT processing occurs first, the value ABC would return
*SEL even though the OMIT of AB* would cause any other ABx value to
be omitted.
If a NAME such as XXX is passed to CHKSELOMT, it is in neither list
and *NON would be returned for non-specified.
It is valid to have only a SELECT list or only an OMIT list.
If SELECT(*ALL) and OMIT(*NONE) are specified, the command returns
normally with RESULT = *NON.
If both lists are used, the CMPCMDLST tool may be used to check the
lists to ensure that no illogical entries have been made.
CHKSELOMT escape messages you can monitor for
---------------------------------------------
TAA9891 The 'position to' key does not exist.
Escape messages from based on functions will be re-sent.
CHKSELOMT Command Parameters *CMD
----------------------------
NAME The name value to be be checked against the lists.
RESULT A required return variable that must be specified as
*CHAR LEN(4). The variable will contain *SEL (the
name was found in the SELECT list), *OMT (the name
was found in the omit list), or *NON (for
non-specified because the name was not found in
either the SELECT or OMIT list).
SELECT A list of up to 300 names or generic names to be
selected. The default is *ALL meaning only OMIT
processing will be performed.
OMIT A list of up to 300 names or generic names to be
omitted. The default is *NONE meaning only SELECT
processing will be performed.
Restrictions
------------
Because CHKSELOMT returns a variable, the command may only be used in
a CL program.
Each list must be passed from command definition (or appear to be
passed from command definition) with the leading 2 bytes describing
the number of entries in binary.
Prerequisites
-------------
The following TAA Tools must be on your system:
CHKGENERC Check generic
EXTLST Extract list
SNDESCINF Send escape information
SNDESCMSG Send escape message
Implementation
--------------
None, the tool is ready to use.
