Re: [Amforth-devel] amforth - how to make him case insensitive

[pito <pi...@vo...>]

Matthias,
the beauty of the forth implementations like amforth or FF on AVR or
PIC is that you do not need other suits of various supporting tools,
just an editor (e.g. teletype or Palm Treo..). The ucontroller shall
contain everything you need in order to operate it.. This is what
most younger fans may attract to. 
So a switch between case sensitivness and case insensitivness woud
be a great feature, as I wrote thre are tons of various source codes
available. 
I am not an avr asm freak so I am not going to dig into your code.
Moreover you might know the code by heart. There must be a simple
point you handle single char from input stream - when the char c is:

((c >= 65) and (c <= 90)) then c = c + 32 ; 
or something like that..

Pito.
