The $ZGETSYI function returns an item of information about a VMS system. The $ZGETSYI function is analogous to the DCL lexical function F$GETSYI.
The format for the $ZGETSYI() function is:
$ZGETSYI(expr1[,expr2])
The first expression specifies the item keyword identifying the type of information $ZGETSYI() returns; keywords may be upper-, lower-, or mixed-case.
The optional second expression specifies the target node; if this argument is missing or null, $ZGETSYI() returns information about the current host system.
$ZGETSYI() provides a tool for examining operating system parameters from within GT.M.
