Choice of Required Parameters

When you see a vertical list of parameters as shown in the following example, you must choose one of the parameters. This indicates that one entry is required, and only one of the displayed parameters is allowed in the statement.

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

►►─ COMMAND ─┬─ PARM1 ─┬──────────────────────────────────────────────────────►◄
             ├─ PARM2 ─┤
             └─ PARM3 ─┘

You can choose one of the parameters from the vertical list, such as in the following examples:
