cobol jcl query

Post by Ashok23 » Thu Feb 02, 2017 10:32 am

Hi all,

I recently got across a question which is-
We have two flat files - File-A and File-B(content of which are below)
----------
File-A
----------
103AA
108BB
111EE
150XX
-----------------
File-B
----------
103AA
111EE
116GG
187JJ
-----------------

So the questions are -
1) You have to use these two files and create a file which contains File-A -(minus/subtraction) File-B records i.e.,108BB and 150XX ?
2) You have to find File-B - File-A?
3) Find File-A Intersection file-B.(records present in both files and records should not be repeated)?

In how many ways this problem can be solved???

Thousands of ways. Millions. Bit of a silly question.
