Since CR as a constant is not documented anywhere that I can find in
my docs, I'm looking for someone on the various non-Mac OS X
platforms to run the following statement in their message box (on
windows, on Linux/Unix, on Mac OS 9) and return the results. Just
want to make sure CR really does vary with each platform.
put the number of chars in CR
put chartonum(char 1 of CR)
and if the number of chars is more than 1
put chartonum(char <x> of CR)
Sorry to be such a pest, I'm not getting my data from a text file,
I'm not getting my data from a URL, I am getting it via a database
connection and unless I manually muck with the text, it will not
display properly. If there are changes to the text, I have to
manually convert it back to what the database expects so that it gets
stored properly. I cannot use these silent behind the scenes
"Revolution will do it for you" kinds of file saves.
Thanks all for the help.
