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.
