Security and the System/38 Environment

This section provides information about security in the System/38 Environment.

The System/38 Environment and CL programs of type CLP38 represent a potential security exposure. When a non-library qualified command is entered from the System/38 Command Entry screen, or invoked by any CLP38 CL program, library QUSER38 (if it exists) is the first library searched for that command. Library QSYS38 is the second library searched. A programmer or other knowledgeable user might place another CL command in either of these libraries and cause that command to be used instead of one from a library in the library list.

Library QUSER38 is not shipped with the operating system. However, it can be created by anyone with enough authority to create a library.
