Any script that runs things in the correct order, piping the output of one 
function to the next in the proper order, will suffice.  The 'cc' 
architecture, while compiled, is very versatile, and I have placed the  
cc252.lzh archive on my web page shown below.  You can rebuild it to suit 
if it doesn't do what you want.

Ansifront012, AIUI it, should not ever have its mind blown as it is 
essentially a void to int translator, just treating the serial text stream 
that goes through it, making the appropriate substitutions.

Your apparent problems with it are really telling me that you are probably 
using the original c.prep that came with the compiler, and that utility 
chokes and passes garbage on to the rest of the compiler when the src code 
file size exceeds nominally 10k in size.  It is patently incapable of 
building a working rzsz-3.3.6, or even the original 3.1.6 version of it.  
That was one of the reasons that it was the subject of a re-write by a comp 
sci student way back when, who took it to the version 1.5 or 1.6 level.  
His code was very well organized, which allowed me to continue it for a bit 
after he got an A & went on to other things.  My final release that I know 
works for src code bases up to at least 36k, is known as cprep19.  It is 
available several places on the net, including my own machine at 
<http://gene.homelinux.net:85/gene/Genes-os9-stf> as cprep19.lzh

I don't proclaim that it will build all of your code, but it is at least 
worth the try.

If you are going to be doing transcendental math functions in C, I have the 
trig.l stuff in that same directory.  The .l stuff goes in /dd/LIB so the 
compiler and cc can find it.  This does trig functions to about 16.5 digits 
accuracy over an EE range of +-EE38 or so. There is a src package and a 
read.me.re.trig.l text file too

See also CnoY, for code intended to be run on a coco3 only, and a Copt2 
intended to do a bit more if it can if placed after the original c.opt, see 
the help message from cc (252) for additional hints once it is unpacked.

Yelp if you need anything else Michael, I probably have it squirreled away 
someplace.  Finding it might take a while though. ;-)
