As part of my current work, I happened to run into a scenario where Representing JCL steps as CI/CD stages—what patterns worked? Thanks in advance for any pointers.

I have been working on Idioms for small string edits efficiently—indexing vs built-ins? Appreciate any ideas or examples you can share.

I've been working on something similar and ran into a few doubts. Seeing different rounding/precision between COMP and COMP‑3. How do you choose types to avoid bugs? Thanks in advance for sharing your thoughts.

Has anyone here faced something similar or have a suggestion? when do you prefer static vs dynamic calls in large systems? Impact on performance, maintenance, and packaging? Thanks in advance for any pointers.

I have a situation in which A report SELECT keeps escalating CPU. How do you profile COBOL+DB2 queries—EXPLAIN, RUNSTATS, indexes—what’s your go‑to sequence? Thanks in advance for any pointers.

Hello Forum,

I’m dealing with a report where a SELECT is driving up CPU. How do you usually approach profiling COBOL + DB2 queries—EXPLAIN, RUNSTATS, index review? What’s your go-to order of attack? Appreciate any ideas or examples.
