Ther is a big difference between AngelScript and VC about shit operation. For a example: uint8[] buf={1,2,3,4,5,6}; uint32 version; version = buf[0]<<24; <<== AS won't expand to uint32, so version is 0 version |= buf[1]<<16; version |= buf[2]<<8; version |= buf[3]; In VC, it will expand uint8 to uint32, so the version=0x01020304; buf in AS, version=0x00000004; Could it be possible to expand type when operator of shit instruction is larger than 8 ? Thanks a lot.

use cast<uint>() ?

I do not try to do this :)

I think you may have discovered a bug in AngelScript. The shift operators should indeed result in 32bit integers if the left operand is <= 32bit.

I'll investigate this tomorrow.

It was indeed a bug, one that I've fixed now. The correction is available in SVN revision 255.
