Example:
GTM> WRITE $ZSETPRV("TMPMBX")
TMPMBX
GTM>
This uses $ZSETPRV() to (attempt to) enable the TMPMBX privilege. The display from the WRITE command shows that the privilege was already enabled when the function executed.
Example:
SET savprv=$ZSETPRV("SYSLCK")
IF '$ZPRIVILEGE("SYSLCK") WRITE !,"Inadequate Privileges"
ELSE DO ^%ST
SET savprv=$ZSETPRV(savprv)
This uses $ZSETPRV() to attempt to enable the SYSLCK privilege. Then $ZPRIVILEGE() checks to determine if the privilege was granted. This controls whether to issue a message or run the %ST utility program. Finally, the routine restores the original state of the SYSLCK privilege that was stored in savprv by again using $ZSETPRV().
