TIPS for novices: When transferring non-text files, such as ARC, ZIP, ZOO, TAR, SIT, and Z files, you must use binary mode, for most ftp programs, you can just type 'binary' before doing the transfer. For some programs, you specify 'image' mode. You must also specify binary mode when downloading to a micro. Most communication programs do not default to binary mode. For example, the UNIX kermit program requires the "-i" option when downloading binary files. You may need to set your terminal emulator to 8 bit data instead of 7 bits. The mac files are MacBinary files. Make sure your terminal emulator is set to download files in MacBinary mode. If you happen to be on a 36-bit machine machine, such as a DEC-20 running TOPS-20, then you should use 'tenex' mode when transferring binary files. A .tar.Z file can be extracted by either of the following: uncompress file.tar.Z (also: compress -d file.tar.Z) tar -xf file.tar or by zcat file.tar.Z | tar -xf - The second is often faster, and may use less disk space. If you don't have 'compress' on your machine, there is a copy of the sources in this directory. This assumes you have access to a UNIX machine. On other machines, it may or may not be possible to decode these files. If you don't happen to have the right decoding programs for your micro, then you can get them from: Mac -- sumex.stanford.edu IBM-PC -- simtel20.arpa (officially known as wsmr-simtel20.army.mil), grape.ecs.clarkson.edu Atari ST -- terminator.cc.umich.edu Amiga -- uxe.cso.uiuc.edu Jim Wilson wilson@kukulcan.Berkeley.EDU
