Environmental Recording, Editing, and Printing (EREP) program is a diagnostic application program that runs under MVS, VM, and VSE. It generates and prints reports from error recording data set (ERDS) records. With these reports, IBM service representatives can determine the existence, nature, and location of a problem.

This topic describes changes to the tape subsystem exception, event history, system error summary, and emulated device summary reports of the EREP program to support 3592 Model E05 tape drives.
