Accessing MVS Static System Symbols

The standard MVS static system symbols include the following:

• &SYSALVL
• &SYSCLONE
• &SYSNAME

Other symbols is defined through the SYMDEF argument in the SYS1.PARMLIB(IEASYMxx) member.

You can use the following operating system command to display these symbols:

D SYMBOLS

These symbols are made available to any NCL application.

To access the static system symbols from a NCL procedure, use $CAPKBIF procedure. The procedure supports the following call types:

• $CAPKBIF PARMS=(PLEXSUB...)
• $CAPKBIF PARMS=(PLEXSYM,,COUNT)
• $CAPKBIF PARMS=(PLEXSYM,symbol,NEXT)
• $CAPKBIF PARMS=(PLEXSYM,symbol,VALUE)

Return Variables:

If &RETCODE is set to 0, the &$CAVALUE variable contains the returned value.

If &RETCODE is not zero, an error has occurred and &SYSMSG will contain the error description.

If &RETCODE is set to 8, an error has occurred. Details of the error are contained in variables as follows:

• &$CAERRORTEXT contains the error description.
• &$CAERRORCODE contains the error code.
• &$CAERRORCOND contains the error condition.
• &$CAERRORSUBN contains the substituted variable name.
