ESP JCL "IF" and "COND" STATEMENTS

• ESP Workload Automation

Issue/Introduction

We hit a JCL flush on our IF and COND JCL statements.

Tested the following.

JOB1

//ESPCCCHK EXEC PGM=CYBES080,PARM=ESPGRPI             ====     RC=0
//STEPLIB  DD   DISP=SHR,DSN=PROD4.ESP.R12M0SP0.CD7YLOAD
//         DD   DISP=SHR,DSN=PROD4.PVAL.R14M6SP0.CBA3LINK
//SYSPRINT DD   SYSOUT=(,)
//SYSIN    DD   *
//STEP10   EXEC PGM=IDCAMS                                                   ====     RC=12                               
//SYSPRINT DD SYSOUT=*
//SYSIN    DD *
// IF STEP10.RC EQ 12 THEN                                                        ====     FLUSH
//STEP20   EXEC PGM=IDCAMS,COND=(0000,EQ)
//SYSPRINT DD SYSOUT=*
//SYSIN    DD *
// ENDIF

JOB2
 
//ESPCCCHK EXEC PGM=CYBES080,PARM=ESPGRPI            ==== RC=0
//STEPLIB  DD   DISP=SHR,DSN=PROD4.ESP.R12M0SP0.CD7YLOAD
//         DD   DISP=SHR,DSN=PROD4.PVAL.R14M6SP0.CBA3LINK
//SYSPRINT DD   SYSOUT=(,)
//SYSIN    DD   *
//STEP10   EXEC PGM=IDCAMS                                                 ==== RC=12
//SYSPRINT DD SYSOUT=*
//SYSIN    DD *
// IF STEP10.RC EQ 12 THEN
//STEP20   EXEC PGM=IDCAMS                                                 ==== RC=12  (COND=) statement removed
//SYSPRINT DD SYSOUT=*
//SYSIN    DD *
// ENDIF

Environment

This is standard MVS JCL but impacted a job where ESP places a CCCHK step into STEP1 which always give RC=0.

Cause

Using JCL COND statements and IF statements together is RISKY at best.

Resolution

JCL IF and COND statement conflict.
ESP not involved.  JCL is working as designed.
