--- TIC-TECH message:
Thank's Doug for some very good guidelines. Another safe type of file is
.rtf (Rich Text Format). This is a universal format for word processing
files that allow the files to be used on either Macintoshes or PC's and to
be backword and forward compatible with older and newer versions of the
software, and to cross from program to program like Works to Word to Word
Perfect, etc. The files turn out larger than the plain *.doc files but
they can't hold word Macro Viruses. I always use .rtf format since I often
switch between platforms and between different versions of software.
