Hi All,

we are having serious problem, can somebody please tell us if by using PROCESS ARITH(EXTEND) will we have any logical problems in the existing program.

We are using PROCESS ARITH(EXTEND) option in our modules to access the extended length of COMP-3 variable, i.e. more than 18.

By using the same option in the program where the comp-3 length is 18 only will it create any problem in the logic

Thanks & Regards

I can't answer directly, but why don't you code a short program and compile it with and without the PROCESS statement and look at the generated assembler code for moves and adds and computes?

Hi William,

Thanks for your reply. I have one more small query while using this option will it have different storage allocations

Thanks & Regards

That too, you will be able to see in the compile listing.
