This should be fixed in https://github.com/avishek-sen-gupta/cobol-rekt/commit/726a7fe5a5cf7f3ccf8c813405d5f159cf38e2c4

The CFG builder wasn't handling the ADD TO GIVING variant. The evaluating interpreter will still need to handle it separately, so I will open a TODO for that. But flowchart generation will work with this fix.

avishek-sen-gupta commented 3 months ago

Closing this, as the flowchart issue is fixed.
