Is this an exercice or a real requirement ?
Is it a sequential or a VSAM file ?
Do you have to do this in COBOL ?
Do you have other things to do on the file/records ?
Is the number binary or packed ? Give record layout.

it's flat file, it's real time scenario only. using that file i am going to load into my table. Actually table is having 1st set of records. I want load 2nd set. if i use same sequence it will discard. i want this thru jcl.

You persist in NOT answering questions. Your first post states the sequence numbers are 2 bytes, yet you then talk about 100, 101, 102 ... which are THREE bytes. So are you using binary (COMP) or packed decimal (COMP-3) to store the values or another coding scheme you did not bother to explain, or are you just planning on violating the laws of mathematics and physics?

Next, you posted in the COBOL forum yet you say you "want this thru jcl" (sic). If you did not want a COBOL solution, why post in the COBOL forum?

Third, JCL does nothing but execute programs. Hence what you want to do cannot be done at all, period. If you had wanted to do this in a batch job using SORT, for example -- that's something very different (and terminology is critical in IT where similar terms may mean very different things -- running a batch job using SORT is NOT the same as doing something "thru jcl"). But as you stated your problem, it cannot be done.

OK, flat file I understand - QSAM.

"real time scenario only" - what do you mean by that?

"table" - what do you mean by that? DB2?

Hello,

Does your subject (How to edit hexa value in the file) have anything to do with what you are trying to do?

As you seem to be lost and are unwilling to post sufficient info for us to help, suggest you implement usng COBOL . . .
