Does anyone know of a Crunching/Squeezing/Zipping-type method of compressing ascii files, that would work under CP/M as well as either MSDOS or UNIX? If so, is the relevant software available in the public domain? The reason for my inquiry is that I have an occasional need for transferring textfiles created on my Amstrad CP/M machine at home, on 3-inch (*not* 3.5-inch!) diskettes, to an IBM-PC machine at work. I achieve this via modem+kermit to the University mainframe, at 300 baud, which which takes forever and costs lots. (I subsequently download from the mainframe to a PC, at 9600 baud, which is fast and free, so that step is trivial). Any way of reducing the file size for the modem transfer would obviously be very beneficial! My only other options are to buy expensive auxillary hardware and transport disks to and from work, or to take up weight-training and carry one of the computers instead... Any help would be much appreciated. David Pickles andmp@uk.ac.bristol.np1a
