DCL-command
Specifies a DCL command which is then executed in a subprocess.
Control is returned to the debugging session when the DCL command
terminates.
If you do not specify a DCL command, a subprocess is created
and you can then enter DCL commands. Either logging out of the
spawned process or attaching to the parent process (with the DCL
command ATTACH) returns you to your debugging session.
If the DCL command contains a semicolon, you must enclose the
command in quotation marks ("). Otherwise the semicolon is
interpreted as a debugger command separator. To include a
quotation mark in the string, enter two consecutive quotation
marks ("").
