JCL - Positional Parameters

---

A positional parameter consists of:

• Characters that appear in uppercase in the syntax and must be coded as shown.

• Variable information, or

• A combination.

For example,

1. DATA on a DD statement.

2. programmer's-name on a JOB statement.

3. PGM=program-name on an EXEC statement.

---

Code positional parameters first in the parameter field in the order shown in the syntax.

If you omit a positional parameter and code a following positional parameter, code a comma to indicate the omitted parameter.

Do not code the replacing comma if:

• The omitted positional parameter is the last positional parameter.

• All following positional parameters are also omitted.

• Only keyword parameters follow.

• All positional parameters are omitted.
