ESCAPE
Allows the CI programmer to simulate all aspects of CI error handling. (Native Mode)
Syntax
ESCAPE[ [CIERR=] errnum ]
Parameters
ERRNUM Sets the CIERROR variable to the absolute value of errnum and the
HPCIERR variable is set to errnum.
Operation Notes
The ESCAPE command causes control to leave all user commands (regardless of nesting
levels) and return to the CI. Batch jobs terminate (unless a CONTINUE is in effect) and
sessions issue the prompt.
If no CONTINUE is active, ESCAPE causes the CI to act as it would for any error: for sessions
the user command environment is cleared and the prompt is displayed; jobs terminate.
If CONTINUE is active , then ESCAPE causes the CI to execute the second command after the
CONTINUE. In the following example, the CI will execute cmd2 after the ESCAPE.
cmd1
CONTINUE

ucmdA
