hello, today, i've made a basic function set to change the case of chars.
it takes the modifier from a 256 bytes LUT, and it translates the char.
then, of course, it is using the charset of européan letters. with accents, etc...
let's go!!
;;change case:
;usage:
;
;force lower case:
; mov al,char
; call case.low
;
;force upper case:
; mov al,char
; call case.up
;
;inverse case:
; mov al,char
; call case.inv
case:
;al=char
;trashes eax,ebx
.low:
mov ah,al
mov ebx,.lut
xlatb
or ah,al
mov al,ah
ret
.up:
mov ah,al
mov ebx,.lut
xlatb
not al
and ah,al
mov al,ah
ret
.inv:
mov ah,al
mov ebx,.lut
xlatb
xor ah,al
mov al,ah
ret
.lut:
