Each time BCONMDMP.PRG is started it will write a file named BCONMDMP.BIN
to the default directory.  Any old such file will be overwritten.
The file has the following structure:

Offset  Type      Description
------  --------  -----------
  00      long    The value returned by the Bconmap(-2) call.  (-> BCONMAP)
  04      long    The ptr to MAPTAB (from BCONMAP)
  08      long    The count of MAPTAB entries (extended to long)
  12    6 longs   The first MAPTAB entry
  36...   ''      Further MAPTAB entries
  
  It is easiest to view this table in a hex editor set for handling
  12 data bytes per row.
