I want to load a file into memory. I am acquiring required amount of memory using getmain. But I don't have any idea of how to load data from file to this acquired memory. icon_question.gif

Why do it this way? Why not use CICS Datatables?

If you really want to do it manually, just read the records and assign each into the next available area in the memory you have acquired, incrementing through the memory as you go.

Hello,

It might be easier to code, but is not a good approach. . .

Suggest you consider a different approach (unless the file only contains 10 records or so).

If this is a read-only file (which is what is being assumed), get together with your Systems folks and ensure that they place this file into an LSR pool, especially if it's high-use.

Other than what Garry had spoken of, regarding data-tables (best choice for read-only), LSR is the second best (read-only or not).

CISZ modification might be in order as well.

Bill
