     The documentation that is in P2DOS.LBR is very scanty. Here is a very
brief rundown of some of P2DOS's features.

     o Written in Z80 rather than in 8080. Makes it smaller and presumably
       faster.

     o Supports an RTC through an extra BDOS call. Also supports date & time
       stamping, with the correct routines in your BIOS ( which the docs do
       *not* elaborate on ).

     o Supports Public files through one of the unused attribute bits ( #2, I
       think ). Any file set to a SYStem file, and with this atttribute set,
       can be accessed from any user area.

     o Supports a path-search feature akin to ZCPR3's, except at the BDOS
       level, rather than that of the CCP. Only SYStem files can be found in
       this way.

     o Expanded error messages. You are now told what the error is ( normal
       BDOS message ), what BDOS function caused the error, and the file
       involved, if any.

     I have had the combination of P2DOS and ZCPR3 running on my Ampro for
over a month now, and have noticed no bugs. On the other hand, I'm not using
all the features listed above.
