Getting online help for z/OS Debugger command syntax

You can get help with z/OS® Debugger command syntax by either pressing PF1 or entering a question mark (?) on the command line. This lists all z/OS Debugger commands in the Log window.

To get a list of options for a command, enter a partial command followed by a question mark.

For example, in full-screen mode, enter on the command line:

?
WINDOW ?
WINDOW CLOSE ?
WINDOW CLOSE SOURCE

Now reopen the Source window with:

WINDOW OPEN SOURCE

to see the results.

The z/OS Debugger SYSTEM and TSO commands followed by ? do not invoke the syntax help; instead the ? is sent to the host as part of the system command. The COMMENT command followed by ? also does not invoke the syntax help.
