The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
Output Screen Command
Use the Output Screen command to make the program output
screen temporarily visible. You can then refer to your
program's output quickly as you edit or debug. The
output screen remains visible until you press any key
or click the mouse.
