DCPU-16 Bitwise Shifting

I am trying to learn DCPU.

;Set b to 1
SET B,1 ;00001 (1)
SHL B,1 ;00010 (2)
SHL B,1 ;00100 (4)
SHL B,1 ;01000 (8)
SHL B,1 ;10000 (16)

All I am doing is shifting to the left one so shouldn't it simply double itself each shift. In my code you can see i have the last shift turning the registry B into 16 but when ran B ends up as 10 why is that.

the register window says 0x0010...

You're getting the correct answer, you're just viewing it in hexadecimal.

Numbers starting with 0x are the standard way of signifying a hexadecimal number; so the number 0x0010 is is really the number 1016 ("one-zero in base sixteen"), which, in decimal, is the number sixteen.
