Tape macros

Real-time and general tape macros provide the operational program with single file, multivolume tape input and output.

To fulfill different system requirements, two distinct I/O capabilities are provided. The real-time tapes are intended for logging system changes, system performance, and other dynamic maintenance information in the real-time environment. The general tapes provide the tape writing, reading, and searching capabilities required by utility programs.

All tapes need a symbolic 3-character name. The first 2 characters must be alphabetic, and the third must be alphabetic or numeric. Additionally, the first 2 characters for a general tape name cannot be RT.
