Hi All,

I have a FB file of record length 100 bytes. At the 19th position file contains an indicator which is populated with P, I and A.
I need to write a cobol program to determine that the records are always coming in the same sequence i.e. first P then I and then A. If the sequence breaks then write entire record should be written to exception file.
We can use account number (first 8 bytes) and security number (next 5 bytes) as key from input file.
Please help me with this

Thanks

Why don't you sort these keys into this order????

And you don't ask newbie questions in a forum for experts, wasting our time!

Before coding COBOL or whatever else you need first of all to create in your mind a plan, or an algorithm: how can you achive your goal?

Without having this in your mind, neither COBOL, nor SUPER-COBOL would help you…
