Choice of Optional Parameters

If you have a choice of more than one optional parameter, the parameters appear in a vertical list below the main path.

The following is a diagram of a statement with a choice of optional parameters:

►►─ COMMAND ─┬─────────┬──────────────────────────────────────────────────────►◄
             ├─ PARM1 ─┤
             └─ PARM2 ─┘

You can choose any of the parameters from the vertical list, or you can write the statement without an optional parameter, such as in the following examples:

COMMAND
COMMAND PARM1
COMMAND PARM2
