Ignore Breakpoint or Action Requests, or Signals
ignorecommand lets you temporarily suppress action and breakpoint requests that you may want to reinstate later. It also lets you ignore signals.
It is better to drop a request than to ignore it because run-time
overhead may be associated with ignored requests, but not with dropped ones.
Format 1: Format 1 lets you ignore breakpoint or action requests at specified hooks. See Using Debugger Commands for details on the HOOK-TYPE argument, an argument that allows you to specify hooks.
Format 2: Format 2 causes the debugger to ignore all signals.
Format 3: Format 3 causes the specific signal named in SIGNAL-NAME to be ignored when SIGNAL-NAME is used with the signal keyword. SIGNAL-NAME is the name of a signal. Tracing of the signal is turned off. See Chapter 17, "Signal-Handling Functions," in the SAS/C Library Reference, Volume 1, for a list of signal names.
Ignoring signals: Format 2 and Format
3 allow you to ignore signals. Whenever a signal occurs, it is traced automatically,
and the return from signal handling is traced also. The
ignore command provides a way to turn off this trace. If you choose
to ignore a signal, the debugger does not trap or trace the signal, and you
cannot recover or resume execution afterward. You must remember this point
when you use
ignore with the signal keyword.
Dropping ignore: You can drop the
command (using the
command) if you want the breakpoint requests and actions to be in effect again
or if you do not want to ignore signals.
Identical requests: If an
ignore request is made that is identical to an existing
the identical request is not installed. This is true whether the request to
be installed is within an
on command or typed
in at the command line.
If an identical request is issued and the original request is disabled, the identical request is discarded and the original request is automatically enabled without an indication.
