Default Value for a Required Parameter

When a required parameter in a syntax diagram has a default value, the default value appears on the main line with a left-facing arrowhead, and it indicates the value for the parameter if the command is not specified. If you specify the command, you must code the parameter and specify one of the displayed values.

►►─ COMMAND ─ PARM1= ─┬─ YES ◄ ─┬─ PARM2 ─────────────────────────────────────►◄
                      └─ NO ────┘

If you specify the command, you must write one of the following:

COMMAND PARM1=NO PARM2
COMMAND PARM1=YES PARM2
