:DEBUG command 

PRIVILEGED MODE 

Enters Debug from the CI. Syntax 

     :DEBUG [commands]

Parameters 

commands         A series of Debug commands to be executed before the
                 Debug prompt is displayed.  The string may be up to 255
                 characters long.  All text on the command line following
                 :DEBUG is passed unaltered to Debug.  Note that the
                 commands should not be quoted.

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
