Job Entry Subsystem 1

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]
