In the COMMAND field of the logon panel, you can enter a single
command of up to 80 characters long.
Note: - TSO/E executes the command you entered after any command
the TSO/E administrator entered in the PARM field on the EXEC statement
of the logon procedure. This would be followed by any commands
found on the data stack.
- TSO/E does not execute the command you enter in the COMMAND
field of the logon panel if the command specified in the PARM field
of the logon procedure fails. For example, the command you enter
fails if TSO/E cannot find the command in the PARM field.
