Specifying OCL instructions

To correctly specify OCL instructions in your JCL, observe the following rules:
  1. When you specify two or more REXX instructions on the same line, separate one from the next by a semicolon followed immediately by one or more blank characters (; ). For example: 
         IF VAR1 = 'OK' THEN ADD APPL(TEST01); ELSE GOTO ESCI
  2. Specify all the instructions in column 1 through column 72.
  3. If the instruction continues on the next line, end the first line with a comma (the continuation character). For example: 
    IF RESULT > 0 THEN,
  DEL APPL(TESTAPPL2)
IF SUBSTR(VAR2,3,1) = '0' THEN COMPL APPL(TEST03);,
  ELSE ADD APPL(TEST04)
  4. If you continue a list of keyword values on the next line, end the first line with two consecutive commas (,,). For example: 
    CHKAPPL APPL(TEST01,TEST02,TEST03,TEST04,,
  TEST05)
  5. If you need to use IBM Z Workload Scheduler-managed variables, specify the JCL tailoring directive (for example, //*%OPC SCAN). These variables will be substituted by the scheduler before it runs the OCL program. For example: 
    //… JOB …
//*%OPC SCAN
//…
//EQQOCL.SYSIN DD *
if substr(&OYMD1,5,2) = 31 then goto lastdd
⋮
    In this example, the scheduler substitutes &OYMD1 with the occurrence input arrival date in YYMMDD format.
  6. Prefix a comment line with an asterisk (*). For example: 
    //EQQOCL.SYSIN DD *
* This is my comment line
⋮
  7. The following instructions store their return code in the variable RESULT:
    ADD ADDOP ADDPRED ADDRES ADDRES
    CALL CHGEXTNAME CHKAPPL CHKDTE COMPL
    CHGJOB CHGOPSAI COMPL DEL DELSIMP
    DELPRED DELRES FORCE HOLD MODCOND
    JSUACT KILLJOB KILLREC MODOP RELSUCC
    NOP OPSTAT RELEASE RELOP
    RELSUCC SRSTAT UNNOP WSSTAT
    For example:
    CHKAPPL APPL(test01,test02)
IF RESULT = 0 then …
  8. Do not include delimiters, such as parentheses, in descriptive fields, such as DESC and EXTNAME.
