 =======================================
 Changes in CPMD 48R4

 - Added BCD dumping command, for Binary Coded Decimal format used by
   Fixed Point Decimal instructions on the 2200.
 - Modify PR and LPR commands to detect if bank being dumped is Extended Mode.
   Add BPR command to force Basic Mode dumping.
 - If an absolute is interrupted while in an Extended Mode bank, that bank will
   be shown as being "based" on B0. REENT will work as usual.
 - Add 5th field to BASE command to allow basing banks on MI, MD, UI, UD, and
   B0 (simulated).
 - Ensure REENT command uses Extended Mode format instructions (EPR) if error
   occurred while in Extended Mode.
 - Improve some Extended Mode instruction dumping formats, such as B-Registers.
 - Modify DWT to handle dates up through 2091.
 - Detect if program was in quarter word mode when interrupted.

   O 040000,60,3

 =======================================
 Patched CPMD 48R1C - 2008/05/01

 =======================================
 Changes in CPMD 48R1C

 - Add DWT command, to dump DWTIME$ value as time & date.

 =======================================
 Changes in CPMD 48R1B

 - When CPMD cannot find the original absolute as named in the DIAG$ file,
   it will display the complete filename.absname it is looking for.
 - Honor D & F options on REENT command.
 - Document R dumping option for relative addresses in HELP DUMP.
 - Add Z dumping option to number words starting from 0.
 - Recognize terminal column width greater than the standard 80 if FUSION on.
