Hi Rob,
The values in a word/dword arein the following format....
byte mirrored not bits...
Intel - DWORD (32-bit) 0x11223344
Motorola - UInt32 (32-bit) 0x44332211
Intel - WORD (16-bit) 0x1122
Motorola - UInt16 (16-bit) 0x2211
Win32 (intel) Assembler Routines...
;*********************
;
; INPUT: eax = source word
; OUTPUT: eax = output converted word
; Registers Destroyed : eax, ecx, edx
;
;*********************
DWordConvertBetweenMotorolaAndIntel proc
push ebx ; save ebx
mov edx, eax
mov ebx, 0FF000000h
and edx, ebx
shr edx, 24
mov ecx, eax
and ecx, 00FF0000h
shr ecx, 8
or edx, ecx
mov ecx, eax
and ecx, 0000FF00h
shl ecx, 8
or edx, ecx
pop ebx ; restore ebx
and eax, 000000FFh
shl eax, 24
or eax, edx
ret
DWordConvertBetweenMotorolaAndIntel endp

; INPUT: ax = source word
; OUTPUT: ax = output converted word
; Registers Destroyed : ecx

;*********************
WordConvertBetweenMotorolaAndIntel proc
mov cx, ax
and cx, 00FFh
shl cx, 8
and ax, 0FF00h
shr ax, 8
or ax, cx
ret
WordConvertBetweenMotorolaAndIntel endp
These are just to give you an idea, you can now easily write C-routines..
...
Hope this helps,

Subject: Palm to Desktop type conversions
