IF/THEN/ELSE/ENDIF statement construct

This topic describes the IF/THEN, ELSE, and ENDIF statements, collectively called the IF/THEN/ELSE/ENDIF statement construct.

Purpose: Use the IF/THEN/ELSE/ENDIF statement construct to conditionally execute job steps within a job.

The IF statement is always followed by a relational-expression and a THEN clause. Optionally, an ELSE clause can follow the THEN clause. An ENDIF statement always follows the ELSE clause, if present, or the THEN clause.

The THEN clause specifies the job steps that the system processes when the evaluation of the relational-expression for the IF statement is a true condition. The system evaluates the relational-expression at execution time.
The ELSE clause specifies the job steps that the system processes when the evaluation of the relational-expression for the IF statement is a false condition.
The ENDIF statement indicates the end of the IF/THEN/ELSE/ENDIF statement construct, and must be coded for each construct.

You can nest IF/THEN/ELSE/ENDIF statement constructs up to a maximum of 15 levels. The steps that execute in a THEN clause and an ELSE clause can be another IF/THEN/ELSE/ENDIF statement construct.
