Resolving File Status and Arithmetic Truncation Mismatches in Easytrieve-to-IMU Conversions
When converting Easytrieve to COBOL via IMU, differences in default arithmetic rounding, file status evaluations, and binary data alignment can cause S0C7 ABENDs or unexpected calculations. Learn how to tune IMU compiler options to ensure exact bitwise equivalence.

Architectural Prevention & Performance Tuning Checklist
- Always compile IMU-generated COBOL with `TRUNC(BIN)` when dealing with binary integers (`USAGE BINARY` or `COMP`).
- Use SuperC with `LONGLN` option to compare numeric columns across 100,000+ output records.
- Verify packed-decimal signs by ensuring `NUMPROC(NOPFD)` is active if legacy data contains mixed signs.
