If you're NEW to the LZH encoding algorithm, you must first extract all of the files in this library via NULU or some other such library utility. The file UCRZLH11.COM is uncompressed and will decode all of the files that are compressed. Merely use the command: UCRLZH11 *.?Y? Z80s only. However, I'm making an update to LT to handle LZH decoding and a program based on FCRUNCH for LZH encoding. Look for those if you require 8080-only opcodes. MOST of the code and docs are based on CRUNCH and UNCRunch. Any typos you find are yours to keep (that is, in modifying/reading/updating the large volume of existing docs for LZH, I undoubtedly have left behind some amusing and/or frustrating half-sentences and such...sorry).
