The only Tape Management Systems currently supported by FATMEN are the HEPVM TMS, and VMTAPE. These are selected by the PATCHY statements
+USE,TMS. and +USE,VMTAPE. respectively.
The Tape Management System is responsible for maintaining information on tape volumes, such as availability, label type etc. When installed without the TMS flag, FATMEN takes the default values for each media type as defined at installation time, or by a call to the routine FMEDIA (or the MEDIA command in the shell).
To see the current defaults, type the command MEDIA in the shell.
As well as tailoring the default values for each media type, a user exit, FMUTMS, can be provided to override the default values for a given volume. See the description of the FMUTMS routine in the user interface section of this manual for more details.
