The only reason I prefer PK*** over }ZOO is that PK*** is, in my experience, about twice as fast. The files }are also better compressed, but the difference is not nearly so dramatic. Most of the speed difference comes from the fact that ZOO is written entirely in C, while PK*** is written mostly in assembler. That's why there are Unix and VMS versions of ZOO, but not PK***. If someone were to recode ZOO in assembly, it would probably be faster than PK*** at compressing, because it would only have to do LZW, rather than doing LZW and in parallel estimating Huffman coding (for "squeezing"). -- {harvard,uunet,ucbvax}!b.gp.cs.cmu.edu!ralf -=-=- AT&T: (412)268-3053 (school) ARPA: RALF@B.GP.CS.CMU.EDU |"Tolerance means excusing the mistakes others make.
