A86 macro assembler, V3.72 September 20, 1994

This package is the new release of the A86 assembler. Please
upload it to bulletin boards, and give it to user groups,
computer departments in schools, and anyone else you think might
be interested in an assembler package for the IBM-PC.
You need to read the manual to use this program -- it's
just too complex to be self-explanatory. The file A02.DOC
takes you through a trial demonstration.
What's New
V3.72 and V3.71 fix a few bugs.
V3.70 adds numerous major features to A86. Let's cover the
INCOMPATIBILITIES first, so you will know where to tweak your
existing code:
* Error messages in A86 now have a slightly different format (on
their own line with a pointer to the error location). If you
have any source code lying around with old-format error
messages, get rid of the messages before reassembling with
this new version -- this version cannot handle them.
I have changed the L switch to the G (code Generation) switch
to prepare for L becoming a Listing-control switch. I have
also changed the X switch to +G16, to prepare for X becoming
the XRF control switch. If you have any batch files or A86
environment-flag settings with +L or +X in them, change them
to +G for this new version.
The DATA SEGMENT now has a default ORG value of END; that is,
it starts at the end of your program, unless you have an ORG
otherwise. V3.20--V3.22 of A86 outlawed ORGless DATA segments,
in anticipation of this feature. Versions before that had a
default ORG of 0 -- if you have source code written for a
pre-V3.20 version of A86, make sure you put ORG 0 at the start
of the first DATA SEGMENT if it was ORG-less.
Other new features include an INCLUDE directive (Chapter 9), a
listing facility (Chapters 3 and 13), END operand value (Chapter
9), pulling XREF and EXMAC functions into the assembler (Chapter
13), operand to EVEN (Chapter 9), the removal of the limit on
the length of a source file, the removal of most restrictions on
forward-references within expressions, the ability to ORG in the
DATA segment and structures to a forward-reference value, the
REF and DEF operators (Chapter 9), the K numeric base (Chapter
10), numeric operands to STOSx and MOVSx (Chapter 5), and macros
in an A86LIB library (Chapter 13).
