Try this --(for intel machines)... atom addr -- Pointer to memory atom val -- peeking val = 256 *peek(addr) + peek(addr+1) --poking poke(addr, {floor(val / 256), and_bits(val, 256)}) --(for non-intel machines)... -- peeking val = 256 *peek(addr+1) + peek(addr) --poking poke(addr, {and_bits(val, 256),floor(val / 256) }) ----- Original Message ----- From: "Jonas Temple" <jktemple at yhti.net> To: "EUforum" <EUforum at topica.com> Sent: Saturday, October 13, 2001 1:24 PM Subject: Poking and peeking C_USHORT > > Okay...here's the question.... > > When a dll function calls for a pointer to an short (signed or unsigned) > what is the preferred method of poking and peeking the data?
