Default Value for a Parameter

The placement of YES in the following diagram indicates that it is the default value for the parameter. If you do not include the parameter when you write the statement, the result is the same as if you had actually specified the parameter with the default value.

The following is a diagram of a statement with a default value for an optional parameter:

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

For this command, COMMAND PARM2 is the equivalent of COMMAND PARM1=YES PARM2.
