Job Entry Subsystem 1 (JES1)

Job Entry Subsystem 1 was released by IBM to provide for VS1 the basic functions that users of VS1's predecessor, MFT, had when using HASP.
Reaction? "Users hated it.".[1] Why? HASP and ASP users often had made local modifications (edits),[2] and wanted to retain their investment.[3]
