Recompiling Easytrieve Programs Resolves S0C4 Abend after Maintenance

Products

• Easytrieve Report Generator

Issue/Introduction

Encounter an S0C4 abend when running pre-compiled Easytrieve load modules after applying new maintenance (such as PTFs for IBM RSU 2512 support). While the existing load modules fail, running the same program dynamically via SYSIN * (Compile-and-Go) completes successfully.

 

Environment

Product: Easytrieve Report Generator 11.6
Operating System: z/OS 3.1

Cause

Applied maintenance can introduce changes to internal structures or module interfaces. Legacy pre-compiled load modules may become incompatible with the updated runtime environment if they do not recognize the new internal code dependencies or shifted memory maps introduced by recent PTFs.

Resolution

To resolve this issue,  recompile the affected Easytrieve programs. Recompiling ensures the load modules are synchronized with the current maintenance level and internal structures of the Easytrieve 11.6 runtime.
