ROFF4, version 1.50

ROFF4, v1.50 is being provided essentially in the
public domain, not because it isn't good, but to provide a
means to create and transport technical documentation
between users with different hardware. This is not possible
with commercial formatters because they are often not
powerful enough to handle special symbols, equations, and
the like. Equally importantly, there is not much
standardization and commercial formatters cannot be "given
away"; the sender and receiver are not as likely to own the
same commercial formatters.
I am a practicing scientist and I need to format
manuscripts which are sometimes long, contain equations,
special symbols, footnotes, and illustrations. I needed a
formatter that was easy to use, flexible, and available to
others. It takes me less time to type a manuscript for this
formatter and rework it, including special characters, than
to have it typed and retyped by a typist only to have me
proof read it ad nauseum.
ROFF4 is table driven; it is relatively easy to
configure for different output devices. I have used it with
the MX-80 and Graftrax printer combination; It is able to
create special symbols where needed. I Also can get special
symbols on my CRT screen because of my computer hardware
(the Exidy Sorcerer has user definable characters).
However, the characteristics of my CRT device and of my
printer are very different. My design philosophy was to be
able to drive either from the same input files so that I
could "preview" my output before going to hardcopy. You may
have a variety of output devices; use your imagination.
Your comments, criticisms, and possible bug reports
will be most useful.
I hope to extend ROFF4 so that it will be able to
better utilize specialty printers (it presently assumes that
the printer does NOT know how to backspace, nor reverse
scroll). I will have to learn how to support printers that
do proportional spacing and variable pitch.
I would also like to write a translater that
automatically converts WORDSTAR(tm MicroPro) files,
including control-P and dot commands into input files for
ROFF4. ROFF4 ignores the parity bit on input files. It may
get confused by inputting control-codes (it should only get
the <CR><LF> and <TAB> of standard CP/M text files).

HARDWARE REQUIREMENTS
ROFF4, version 1.50 was developed with the BDS C
compiler, version 1.44 and the Mark of the Unicorn L2 linker
version 2.2 on an Exidy Sorcerer personal Computer with the
S-100 expansion box. The Thinker Toys 2D dual 8" disk sub-
system was used and total contiguous ram was 52K.
Statistics from the BDS compiler indicated at least 14K left
over at every stage. Thus it may be possible to recompile
this in a 40K system. Tthe linkage statistics are that we
have 127 functions, code ends at 75CEH, and that externals
are from 7800H-91E8H.
To run ROFF4.COM I believe the TPA should be 44K or
more because the alloc() function must allocate slightly
more than 1K for each simultaneously open file and I have
reserved (quite conservatively) 2K for the stack.
I/O requirements are minimal. A dumb terminal (video
or printing) and the CP/M disk interface are sufficient.
Although a list device seems like a practical necessity (do
you want to format only to a glass terminal?)
By all means, read the file, ROFF4.DOC ("when all
else fails, read the manual!") Try out the sample input
files, they are probably better illustration of points where
my writing isn't clear.
Enjoy... (leave the debugging to us).
