SYMBOL MASTER (S/M) provides you
with a full assembly listing print-out
or a source code listing to disk. The
print out or the disk listing format
will vary according to editor/assem-
bler selected. S/M at the present
time will support the following
editor/assemblers:
(1) MAE
(2) PAL
(3) DEVELOP 64
(4) CBM 64
By using one of the monitors
included on the disk and the print-
out, you can develop a source code
listing that may be easily modified
by using one of the above
editor/assemblers. If you want
comments on your source listings or
print-out, you will have to provide
them yourself.
If you have ever wondered how an
auto-boot works so that you could
modify it, then 'SYMBOL MASTER' is for
you. After a little work with one of
the monitors to determine where the
data and tables are in the boot, you
can load the program with an offset
into memory and then print-out the
boot with its original memory
locations to study to your heart's
content.
The disk also contains numerous
examples of machine language programs
and command pages to convert these
programs to symbolic listings. The
examples plus the excellent manual
included with the disk provides a
great training tool for the serious
machine language programmer.
In closing, let me quote a few
lines from a recent Schnedler System's
letter about future upgades; ....Here
is a list of the upgrades planned
for the fall of 1985:
(1) Support for the LADS and MERLIN
assemblers.
(2) The ability to import your own
label names to be used in the
assembly
(3) Enhanced 6502 instruction set,
i.e. 65C02, as a selectable
option
(4) Formatted disk file (word-
processor) output directly from
SYMBOL MASTER
(5) A version specifically for the
C-128 computer in its native
8502 (128K) mode if that computer
is actually available.
