Re: FORMS - Retrieving all filenames from files in a directory (windows)

To get rid of the flashing DOS window, use the NO_SCREEN parameter to the HOST builtin:
  HOST("dir *.txt > myfiles.all /b", NO_SCREEN);

A few weeks ago I did some searching of my own to find another way to get a directory listing, but did not find anything; AFAIK, this is the only way to do this in Forms.
