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 report, emulated device summary report, and TAPE Media Informational Messages (MIMs) of the EREP program to support TS1140 tape drives.
