Hi,
I want to execute one particular step depending on a field value. I have gone through the existing jobs in my prod lbrary and google. It seems we can validate the return code of a particular step through IF condition.
I want to execute a step if field1 not equal to spaces
Can anyone tell me if it is at all possible to check a field value in JCL. And if possible what will be the yntax for this.
I was using
| Code: |
| // IF EMAIL1='' THEN |
but it is not working |

As reading the fine manual would have told you, this is not even close to acceptable.
Now, what is the source of FIELD1 supposed to be? A symbolic variable? A parameter taken from a data set, or output by a program? |

What does the JCL manual say about the IF statement
Look at the top of this page under IBM MANUALS! |

| I looked into the manuals. JCL user guide and JCL language references. What I found there is, expressin can be used in the IF clause. But I am not sure if anything can be use as expression other than RC. Please correct me if I am wrong. |

For the sake of discussion, I assume that a Rexx exec is being used to handle the panel and tailor skeletonized JCL. Add the first two steps at the beginning of your job:
| Code: |
//STEP000A EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD *,DLM=@@
/* Rexx */
trace o
if (&FIELD1=' ') then return 666
else return 0
@@
//SYSUT2 DD DSN=&&TEMP(FOO),DISP=(NEW,PASS),SPACE=(TRK,(1,1,1)),
// UNIT=TEMPDISK,DCB=(RECFM=VB,LRECL=255)
//SYSIN DD DUMMY
//STEP000B EXEC PGM=IRXJCL,PARM='FOO'
//SYSEXEC DD DSN=&&TEMP,DISP=(OLD,DELETE)
//SYSTSPRT DD SYSOUT=* |
Encapsulate the desired JCL thus:
| Code: |
//IF1 IF (STEP000B.RC = 666) THEN
(stuff to be done)
//ENDIF1 ENDIF |

Your reading comprehension seems flawed. z/OS V1R12.0 MVS JCL Reference clearly states:
| Quote: |
| The following keywords are the only keywords supported by IBM and recommended for use in relational-expressions. Any other keywords, even if accepted by the system, are not intended or supported keywords. |
(Emphasis added.) |

I tried the provide code but it I am getting RC=3651. I am not sure if I am missing something. Here is what I am doing.
| Code: |
//STEP000A EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD *,DLM=@@
/* Rexx */
trace o
if (=' ') then return 666
else return 0

//SYSUT2 DD DSN=&TEMP(FOO),DISP=(NEW,PASS),SPACE=(TRK,(1,1,1)),

Hello,

In which step. . .?
Post the diagnostic information generated by the problem step.
If you want people to help, you simply must post something to work with . . . |

I hope you are using a skeleton JCL.
And if yes, why not just do:
| Code: |
)SEL &EMAIL ¬= &Z
.
. place your step here
.
)ENDSEL |
No value = no step. Nothing easier than that! |

| If you are passing the value through a panel then surely your logic which displays the panel and accepts values should also include the logic to either submit the job or not rather than faffing about doing something totally unrequired in a batch job. |

FIELD1 is set to null, not space, on return from the panel, as your output clearly shows.
On consideration,I like Marso's solution better than the one I originally devised; it's more comprehensible. |

There needs to be a SPACE between the variable name and the operator.  |

| Great!!!. Working now. I have one concern. My job has only this step and if the condition is getting satisfied i.e. email id is blank the job is getting JCL error. Is there anything which can be done? |

| We don't, yet, have access to your latest JCL. If you can post it and tell us the details of the error you are getting, maybe there is something that can be done. |

Add a step to your skeleton JCL that executes IEFBR14 - I suspect, but do not know as you have not told us, that the JCL error is something along the lines of 'JOB HAS NO STEPS'.
Time to put your thinking cap on and think about the error and how to resolve it. |

Hello,

So, what was the problem and what fixed it?
If you expect people to spend so much time on your several issues, the least you could do is post what the problem actually was and what fixed it.
You may find less people willing to help if you continue to have these drag-on topics and then provide no followup. . .

| I updated it here as soon as i fixed it. It was giving NO STEP FOUND ERROR. I did as suggested and that worked. I should have given more detail in my earlier post itself. I am really sorry for that. |

In that case, consider:
| Code: |
IF EMAIL <> '' THEN DO
"FTOPEN ..."
"FTINCL ..."
"FTCLOSE"
"SUBMIT ..."
END |
