RTS 115 is a "smoke alarm" for memory issues. By capturing the system state right before the call to external code, you can pinpoint the corruption and restore stability to your application. To tailor this blog post, please tell me: What is the or text inside the RTS0115 file?

Based on technical documentation, typically refers to a COBOL Runtime System Error caused by memory corruption, often occurring when calling C routines within a COBOL application.
Use a dedicated C debugger to run the routine in isolation with the captured values. This often reveals exactly where the memory overwrite occurs.
Since standard core files may be unusable for debugging memory corruption, follow these steps to find the culprit:
If you are seeing the dreaded error in your COBOL application, you aren't alone. This specific "Runtime System Error" is a classic sign of memory corruption. Unlike standard crashes where you can simply check a variable's value, memory corruption often hides its tracks, making traditional debugging difficult. What Causes RTS 115?
Add this routine to your COBOL code immediately before the call to the suspected C routine. This captures the state of the system before the corruption happens.
Isolate the values being passed to the C routine. Check for: Buffer sizes that are too small. Missing null terminators. Incorrect pointer references.
