CMD indicates that the PFK is to have a command or commands associated
with it. command specifies the command. Multiple commands on
a CMD line must be separated with a semi-colon. The maximum length
of the commands including the single quotation marks is 126 characters.
If a command contains a single quotation mark, surround the command
with double quotation marks. If the command contain double quotation
marks, surround the command with single quotation marks. If a command
contains an underscore, define the key as conversational CON(Y). When
the system displays the command, the cursor will be under the character
immediately to the right of the underscore. The system will not display
the underscore. IBM® suggests
that you specify the complete command rather than take any parameter
defaults, since the defaults might change. See z/OS MVS System Commands for
details. JES3 commands
must have an asterisk (*) for a prefix or an alternate prefix as specified
on the CONSTD statement of the JES3 initialization deck. If
you want an underscore to appear in the command, use two underscores.
They are treated as one underscore, and are not used for cursor placement.
