Wilkens): +--------------- | You need the tenex to download a binary file to a UN*X system, since simtel20 | is a VMS system. Once you get the file, just move it to RZSZ0525.TAR.Z, +--------------- Minor nitpick: VMS doesn't require the "tenex" command. The command is named after the OS it supports: "ten-ex", for TOPS10-extended. This is one of a family of operating systems (TOPS-10, Tenex, Tops-20, and Twenex) for the DEC PDP-10 mainframe. The reason it's provided is that the PDP-10 has 36-bit words which don't cleanly split into bytes; ASCII files are stored as 5 7-bit characters per word + 1 spare bit, while octet-oriented binary files are stored as 4 8-bit characters per word + 4 spare bits. The "tenex" command causes ftp to unpack the files properly; "ascii" would do it wrong, and "binary" (AKA "image") doesn't unpack bytes at all. ++Brandon -- Brandon S.
