Hi,
I am new to Mainframe technology and i have requirement like below:
1. I have a flat file which contains the job details with the expanded PROC with dataset name.
2. The datasets has so many JCLS in expanded order.
3. My requirement is to capture all the job names and the datasets associated with the job names.
4. I am planning to use string and unstring concept but not sure how to proceed the coding. Can someone please help?
I am pasting the details of the files below:
//ABCDEFGH JOB .....................MSGCLASS=X,CLASS=
..
...
...
..
..EXEC PROC
...
..
//-- DSN=a.b.c,Disp=shr
..
..
Please note that the position of //Jobname i.e //ABCDEFGH here is not in a particular position and can vary
i want to apply logic like-
a) Read the lines one by one
b) If a line contains the keyword (MSGCLASS or CLASS) or has the keyword JOB then after the "//" symbol it should be job name and i have to capture the job name here ABCDEFGH
c) then i have to capture all the datasets associated to this job name until the next job name comes.
d) please note that to capture the datasets i can use keyword DSN and some other criteria but i am not sure how to implement it.
Can you please help me |

I am not sure if your requirement qualifies to do using Cobol, Might be REXX/Macro will be a better solution.
How big is your flat file?. Is this a one-time/daily/weekly/monthly activity? |

Hi Mfkid,
I am suppose to develop a cobol program for this task. The flat files might contain more than 50000 jobs.  . Even if I have a small and easy Rexx program then I can try to convince them for Rexx. |

| You have been told -- both here and on our sister board -- that a quick, easy solution does not exist. Mr. Myers has pointed out some of the difficulties. You have taken a bite (or had it thrust into your mouth) that is too big for you to chew. |

no small program will be able to parse and extract info from a JCL stream |

Hello and welcome to the forum,
As has been explained, it is not acceptable to post the same question in multiple forums. This topic is being locked.
As your experience level is on the low end, the "other" forum will be more suitable to help you with various kinds of questions.
Be aware that most of us senior "helpers" here support that forum as well, so you will have mostly the same answers anyway.
As explained, this will not be a trivial task (if done well).
If a working solution seems too complicated to download and run, you will be better working on something else until your experience level increases.
