ENDIF Statement

Purpose

The ENDIF statement marks the end of an IF/THEN/ELSE conditional block in JCL. It is required to terminate every IF statement and indicates where normal sequential execution of JCL statements resumes.

Syntax

//[name] IF (condition) THEN
//         statements to be executed if condition is true
[//         ELSE
//         statements to be executed if condition is false]
//[name]   ENDIF

Key Points

• ENDIF is required to close every IF/THEN block
• Each ENDIF is paired with the closest preceding unmatched IF
• JCL execution resumes sequentially after the ENDIF statement
• The name field in ENDIF is optional and typically omitted

//         IF &SYSDAY = 'FRIDAY' THEN
//           IF &SYSTIME > '17:00' THEN
//             SET BACKUP='FULL'
//           ELSE
//             SET BACKUP='INCR'
//           ENDIF  /* End of inner IF */
//STEP1    EXEC PGM=BACKUP,PARM='&BACKUP'
//         ENDIF  /* End of outer IF */

Notes

• Every IF statement must have a corresponding ENDIF statement
• ENDIF statement pairs with the most recently unpaired IF statement
• In nested IF structures, each inner IF must be closed with its own ENDIF before the outer IF is closed
• The name field in the ENDIF statement is optional and is typically omitted
• Normal sequential execution of JCL statements resumes after the ENDIF
• Comments can be added after the ENDIF keyword using standard JCL comment syntax

Common Mistakes

• Omitting the ENDIF statement (required to close every IF)
• Incorrect nesting of ENDIF statements (must match IF statements in reverse order)
• Using END instead of ENDIF (not valid in JCL)
• Placing JCL statements between an ELSE and its ENDIF on the same line
