fasm 1.66 dated 14 june

push 16777215
causes "value out of range".

the intel manual states "Push sign-extended imm32."
im still quite rubbish at asm but doesnt this mean i
can have any positive (or negative) number up to 2 ^ 31 ? as bit 32
is sign bit.

i tested this in MASM and it compiles successfully.

I think that you are in 16-bit mode and you are trying to push a 32-bit value. Are you sure there isn't an error in your code?

Code:

use32
push 16777215
use16

should work fine for you though

Code:

push dword 16777215

would be more elegant

it was the use32, thankyou. it slipped my mind to check that.

it was because the whole source file was simply that instruction
and nothing more. im just seeing what the byte values of
an assembled instruction are.

Code:

pushd 16777215

^ could be used too I think.
