 The actual ZSDOS source code was minimally modified to achieve TASM assembler compatibility.  In order to minimize the number of changes to the source, I created a "wrapper" that defines a bunch of helper macros to improve compatibility.  The wrapper uses a #INCLUDE to imbed the actual ZSDOS source.

I have chosen to use ZSDOS to pick up the maximum number of features.  DateStamping is still available, it just uses memory outside of the OS.
 
 The source also allows you to compile the OS code as either v1.1 or v1.2 via an equate.  This can be controled by the wrapper just like the choice of ZSDOS/ZDDOS.  Version 1.2 has only a couple of small changes versus v1.1 (apparently a minor bug fix).  However, there are warnings in the source that compiling the DOS as v1.2 will make it incompatible with existing overlays and applications.  I encountered this myself with the date stamping code -- won't work with v1.2 because it does a version check.  For now, I have chosen to use v1.1 to maximize compatibility (seems to be what everyone is doing).  Ultimately, I may go back and try to rebuild everything in the distribution to bring it all up to v1.2.  That is for the future though.
