the QSYS.LIB file system would likely have been known as <em>the</em> iSeries server

file system. Programmers who used languages such as RPG or COBOL and facilities

such as DDS to develop applications were using the QSYS.LIB file system.

|
System operators who used commands, menus, and displays to manipulate output
|

queues were using the QSYS.LIB file system, as were system administrators
|

who were creating and changing user profiles.</p>
