Anyone familiar with the ".cq" file format? C source for Lattice or Aztec perhaps?

Hi Atarians,

Tom Hudson mentions in the Ray Tracing Article (Start Volume 1, Number 4) : "If you're a programmer, you'll be glad to know the source files for the TRACER program (TRACER.C and TRACEASM.S) are included on the START disk in the RAYTRACE.ST folder."

 

What I see though, is a file called: "TRACER.CQ" That appears compiled and cannot be read with a text editor. Anyone have an idea?

 

Thank you.

Well I have the answer, I just received the Start magazine from eBay. The "Q" is due to compression used on the cover disks. In retrospect it makes total sense. Anyway, I will scan the missing page and make the issue on archive.org and atarimagazines.com complete.

 

Thank you to anyone who read this.

The CP/M convention is that the letter 'Q' replaces the middle letter of the extension of files compressed with the SQ (squeeze) utility.  Use USQ (unsqueeze) to decompress it.

It's not the usual CP/M "unsqueeze", but "unsqueeg".  There is an UNSQUEEG.PRG on the V1N2 floppy.

 

I used it to extract the FujiBoink source code: https://github.com/larsbrinkhoff/FujiBoink
