Assembler
; R0 = Pointer to string (set on entry)
; R1 = Byte read from string
; R2 = Pointer to lowercase table
HEAD ("lowercase")
|lowercase|
MOV ip, sp
STMFD sp!, {a1, fp, ip, lr, pc}
SUB fp, ip, #4
STMFD sp!, {v6}
MOV R1, R0 ; Preserve string pointer
SWI &43040 ; "Territory_Number"
SWI &43057 ; "Territory_LowerCaseTable"
MOV R2, R0 ; Set lowercase table pointer
MOV R0, R1 ; Restore string pointer
lowercase_loop
LDRB R1, [R0] ; Load character from R0
CMP R1, #0 ; Is it a null byte?
[ {CONFIG} = 26}
LDMEQEA fp, {fp, sp, pc}^ ; Return if null (end of string)
|
LDMEQEA fp, {fp, sp, pc}
]
LDRB R1, [R2, R1] ; Convert to indexed lowercase
character
STRB R1, [R0], #1 ; Store character, increment offset
