Question: I tried taking a Mac file downloaded from CIS, putting it on a MSDOS hi-d floppy (through CrossDOS), then giving it to a Mac user to pull into their hi-d drive-equipped Mac IIcx. They were using Apple File Exchange and said the program was trying to somehow _translate_ the Mac file as if it were an ASCII document or something. Problem is, the file was a program. Is there a way to turn off the translation, and simply copy the file verbatim from the PC-format disk onto the Mac? Regards, Phil Combs
