When compiling LF90 programs from ED, the compiler output is not showing up.

[R. T. (Fortran Man)]

When compiling my LF90 programs from the Editor, the compiler output is not showing up. What could be the problem?

You may have an old ANSI driver on your system which for some reason stops ED from getting program output. If there is a reference to either "Vansi.sys" or "Eansi.sys" in your "config.sys" or "config.nt" file, removing the reference should eliminate the problem.
