System variables used to format error messages

If an error occurs, an error message is formatted before control returns to the function. This list defines the contents of the system variables that are used to format error messages:

Variables: Contents
ZERRMSG: Message ID.
ZERRSM: Short-message text in which variables have been resolved.
ZERRLM: Long-message text in which variables have been resolved.
ZERRHM: The name of a Help panel, if one was specified in the message definition.
ZERRALRM: The value YES if an alarm was specified in the message definition (.ALARM=YES); otherwise, the value NO.

ZERRMSG, ZERRSM, and ZERRLM are changed only when the return code from a DM component service is greater than 8.

These system variables are in the function pool, if it exists. Otherwise, they are in the shared variable pool.

The function can display the message, log the message, or both, simply by invoking the appropriate service with the message ID ISRZ002. For example:

ISPEXEC  SETMSG  MSG( ISRZ002 )
ISPEXEC  LOG  MSG( ISRZ002 )

The service provides the short- and long-message text, the name of the corresponding help panel, and the alarm setting for your use.
