Usage note

In the following cases, z/OS Debugger does not display the syntax help after you enter the ? command:

  • The z/OS Debugger SYSTEM and TSO commands followed by the ? command do not display the syntax help; instead the ? is sent to the host as part of the system command.
  • The COMMENT command followed by the ? command does not display the syntax help.
  • The SET PFx command accepts a ? as the "command" operand and, in this case, does not display syntax help.
