This is a practical application of conditional replacement. I think this subroutine demonstrates how the code works quite well.ToUpper: addlw 255 - 'z' ; Get the High limit addlw 'z' - 'a' + 1 ; Add Lower Limit to Set Carry btfss STATUS, C ; If Carry Set, then Lower Case addlw h'20' ; Carry NOT Set, Restore Character addlw 'A' ; Add 'A' to restore the Character return
