MDCD 1.0 is the first release of a file compression and decompression program that compresses data using a 13 bit LZW
algorithm. It was written in Turbo Pascal and requires the Turbo Pascal 5.0 compiler. Portions are written in 808x assembler and require Turbo Assembler 1.0 or MASM 3.0+.
It is not as fast as PKWARE products but compresses almost as
well. It is significantly faster and compresses better than the only version of
ARC that I could find to compare it against
(version 5.20).
It demonstrates some interesting differences when compared to current file compression/decompression programs. I will talk about the differences in a bit, but first I want to talk about what it is
not...
