Create a comprehensive transformation guide that maps each mainframe dependency to its standard COBOL replacement. This guide is a prerequisite for the actual transformation — DO NOT modify any code, only create the guide. Output Format Document each mainframe-specific construct with: 1. Pattern : The mainframe construct (e.g., ) 2. Replacement : The standard COBOL equivalent 3. Error Handling : How to replicate the mainframe's error behavior - Map CICS RESP/RESP2 codes to FILE STATUS equivalents - Specify which FILE STATUS values to check (e.g., 00=success, 23=not found, 35=file not exists)…
