Re: APL: GNU: Microsoft: Windows: 10: Color

[Dr . Jürgen Sauermann]

Hi Knud,

according to:

https://ss64.com/nt/syntax-ansi.html

Windows uses the same ESC sequences as VT100. Maybe it suffices to 
un-comment
the white on black screen sequences in the preferences file that is 
shipped (and installed)
with GNU APL (the default colors are for black text (aka. foreground 
color) on white (ala.
background color) screens).

Make sure that the preferences file is actually loaded ( apl -l 37 ) 
because cygwin (and also
WINDOWS) uses a different directory structure and therefore GNU APL may 
not find it when
started from cmd.exe. Chances are better in cygwin, though.

Best Regards,
Jürgen
