====== Media Map Access ======

From the BASIC+ or the System Monitor, a media map is accessible via the logical file name REVMEDIA. This name is used for all media maps, regardless of volume or filing structure.

To access the media map, a user attaches the logical file name REVMEDIA for the volume being accessed. For example, to attach the media map for the default (DATAVOL) volume, execute this System Monitor command:

RUN ATTACH_TABLE  "DATAVOL", "REVMEDIA"

The output from a successful [[attach_table|ATTACH_TABLE]] is shown below:

{{datavolattach.gif?409x180}}

From this point, the media map can be accessed using any file or record-oriented command.  For example, rows in the REVMEDIA table can be edited using the System Editor, as shown below:
