Maury, This was the problem. Apparently with M sees a !, it automatically resets $X, but writing a $char(13) doesn't. This seems kind of an odd mechanism.
I was switching back and forth between writing files out to a file and writing the progress on the screen. It seems that there is only ONE $X, not one each for the file and another for the screen. So I had to make the switch between states just after a ! had been written to the file. Thanks for the help. Also, I hadn't known that write *x is the same as write $char(x). So I learn something every day... :-) Thanks Kevin --- Maury Pepper <[EMAIL PROTECTED]> wrote: > It would help to to know what your code looks like > and exactly what you want the output to look like, > but let me offer a couple of thoughts: > > 1.
