With dos, any program can call INT 10 and change the text mode screen.
FORCEXT.ZIP, or some such, I think at GARBO, SIMTEL, FILELIBRARY, et al,
seems to go into the kernel and change the default from 25 to 50 lines,
so that when NC, Neopaint or whoever exits, it comes up with the 50 line
screen. It has a funny bug that changes the high intensity blue to
regular blue underline. unless you're using fancy ansi graphics, that
wont matter.

'Directory Wizard', aka DW-xx.zip, has a config.exe which sets the
default for the file manager to 50, and it'll prolly exit in 50 as well.

Then there's also 'SET60.EXE' which gives vesa svga 60 line text screen.
which your video card might, or might not like, and some software works
with it, some dont.
