I hope I understand as well.

There is not even a point in pseudo-coding it. The use of a large table is the same as the use of a small, or middle-size, or any-sized, table.

To get some heap storage from the Language Environment involves a CALL. Not really worth pseudo-coding. There are readily-available examples of doing this in IBM manuals.

The code that may be additional for a requirement that is actually best-fulfilled by a/some huge table(s) is specific to that requirement, and is out-of-the-ordinary, and it is not much use to invent for a "general" situation when I feel that in almost all cases there are better ways to service the requirement.

Large tales in themselves are not difficult to code. Using LE Heap Storage is not difficult to code. Large tables and large amounts of Heap Storage are not generally good things to use in your environment. If I was doing a "code review" I would not let such a solution go further if there was a better way to do it differently. Which would mean your time wasted and your part of the project late as you have to start again.

Can you provide the solution for learners like me
Sure sounds like you're asking for code here. If not code, what other solution did you mean?

You develop the solution just like any other coding problem in IT -- you look at the outputs you need, you look at the inputs you have, and you determine -- step by step -- the processing required to transform the inputs into outputs. Once you understand the processing well enough (pseudocode helps a lot with this), you can write COBOL (or C or BASIC or FORTRAN or Perl or whatever the language of your choice is) code to implement the processing.

The IBM COBOL manuals (Application Programming Reference and Application Programming Guide) both have many examples of code in them -- for handling tables and files among other techniques -- and you would be well-served by spending the time it takes to go through them, thoroughly. Once you've done that, spending some time in the Language Environment bookshelf pays big dividends as well.
