;Summary:       Converts
;Compatibility: K7
;Notes:         This
;      While doing some light reading of the AMD K7 Athlon Optimization
;Manual, I came across one of the neatest hex-to-ASCII converters
;I've ever seen:

Example 5 - Hexadecimal to ASCII conversion
(y=x < 10 ? x + 0x30: x + 0x41):

MOV AL, [X]  ;load X value
CMP AL, 10   ;if x is less than 10, set carry flag
SBB AL, 69h  ;0..9 -> 96h, Ah.. h -> A1h...A6h
DAS          ;0..9: subtract 66h, Ah.. h: Sub. 60h
MOV [Y],AL   ;save conversion in y
