Hi phil,

I though I remembered it as:

+1 = &b0000000000000000000000000000001 (32 bits signed)
-1 = &b1111111111111111111111111111111 (32 bits signed)

use:
print bin$(-1)


so just moving the sign bit is not going to make up, you need to add 32 "1"-es as well.
Appart from that.. is that faster than ?

if pos!>2147483647 then inc pos!,-4294967296

P.S. a (faster) alternative could be :
x% = (x%<<32)/2^32
