Problem with Returning and linkage section

[Anonymous]

Below is a single program with two sub-routines. The first functionABC works fine. The second, functionABC2 uses the returning keyword but gets this error:

libcob: subProgram.cbl:44: error: BASED/LINKAGE item 'avalue2' has NULL address. I get this error if I use returnvalue or returnvalue2, either one causes this problem.

My build command: cobc --debug -x -free -g subProgram.cbl

I feel like I've tried everything and have followed the programmer's guide to no avail.

Any help please? Thanks!
