Perhaps a little bit better method is to make a shell script to do that
*and* download the file.  Similarly for uploads.  I ended up with fours
files (which I guess would very easily be sent into one with a flag), two
for uploads, two for downs (One is DOS 3.3, the other ProDOS.).

ex:

#!/bin/sh
mkdir /tmp/tmp.$$
for i in $*
do
tr '\012' '\015' < $i > /tmp/tmp.$$/$i.up
done
#either x or y modem works here
ymodem -flags `/bin/ls /tmp/tmp.$$`
rm -f /tmp/tmp.$$
exit 0

Of course, more is needed if you want to do a series of xmodems.

The point is, that in mangling files, it's much better to make the
modifications somewhere else, to *something* else.  This way, the 
modificatons don't muck around with the originals, and you don't have to
remember to do them separately.

(Sorry for all you VMS-types. . .Though I'm sure you could so something
similar.)
