i personally think that a zipping program on the ti-85 is a bad idea. my
reason for this is because even if a 4k program could be compressed to
half its size you would need 4k of memory free on your calculator to run
it because it first has to be decompressed. therefore that program will
take up 6k of memory when you want to run it. also another reason why
this is a bad idea, the compression ratio will most likely not be 50%,
it will probably by more like 10% - 15% because assembler files are
already in a way compressed therefore making the compressed program's
file size would be approx. 3.5k saving approx. 500bytes. also the
decompression program would most likely be to infeasable to have on the
calculator since it would most likely be at least 10k to 15k(this figure
is based on the PC file PKUNZIP.EXE(version is 2.04g registered which is
approx 28k in size) and that would leave enough room for 1 or 2
programs. also note this message is not to stop research into a such
program, it is just here to state my opinion but may also change the
opinions of the people out there. also note that at one time i wanted a
stacker like program for the ti-85 but i eventually realized that it
would be to infeasable because of the memory restrictions of the TI-85.
