:DEBUG Command

Discussion

The :DEBUG command enters Debug directly from the session CI. Optional Debug commands may be entered on the command line, and they will be executed before the Debug prompt is displayed.

If the optional commands contain a Debug command that returns the user to the CI, any further commands are left pending on Debug's command stack. The next time Debug is entered, any pending commands are executed before the Debug prompt is displayed. If no commands were specified, Debug displays its prompt and waits for the user to enter interactive commands. This command is ignored in a job.

Example

The example below calls Debug to produce a stack trace and return to the CI.

   :debug  trace;c
