Variables Representing Several Parameters

In some syntax diagrams, a set of several parameters is represented by a single reference.

The following is a diagram of a statement with variables representing several parameters:

►►─ COMMAND ─┬─────────────────────┬──────────────────────────────────────────►◄
             ├─ PARM1 ─────────────┤
             └─┤ parameter-block ├─┘

Expansion of parameter-block

├──┬─────────────────────┬─────────────────────────────────────────────────────┤
   ├─ PARM2 ─────────────┤
   └─ PARM3 ─┬─────────┬─┘
             ├─ PARM4 ─┤
             └─ PARM5 ─┘

The parameter-block can be displayed in a separate syntax diagram.

Choices you can make from this syntax diagram therefore include, but are not limited to, the following:

COMMAND PARM1
COMMAND PARM3
COMMAND PARM3 PARM4

Note: Before you can specify PARM4 or PARM5 in this command, youmust specify PARM3.
