This is just a minor annoyance for a minority of users, and not worth requiring an additional library and adding a GUI to my otherwise command-line only code.

I am not aware of "overwrite" format in IDL FORTRAN formats.
But you might achieve your goal by mixing with IDL C-style formats.
For instance, doing the following code in a Windows command window, I
can overwrite on a same output line all the 11 numbers, one per
second.

IDL> .run
- for i=0,10 do begin
- print,i,FORMAT='(%"\b%d",$)'
- wait,1
- endfor
- print
- end
% Compiled module: $MAIN$.
10
IDL>

%" ... " are delimiters for C-style format; \b is the escape code for
backspace.
Please refer to the documentation.
