Re: Reading source files in RPGLE

I haven't needed to read a source file for about 24 years and didn't have

Now I need to do it again and am using RPGLE. I can open the file and read
records but the fields are all empty. I must be doing something pretty
dumb. I am on V5R1. Can anyone help please? I have tried with both
externally described and program described files.

If you don't use the fields in your program, the compiler makes an optimization and doesn't move the data from the input record into the fields.

You can code DEBUG(*INPUT) in your H spec to get it to always load fields even if they are not used in the program.

Here's a page in the Programmer's Guide "Unexpected Results when Evaluating Variables"
