I have 16 lines bit that has 0 or 1.

Expected code is like below.

for( i 0 16 then

buf = buf + bit[i]*2^i

)

sprintf(get "%x" buf)

You can do:

2**i
expt(2 i) ; this is exactly what 2**I does - it's the functional equivalent
pow(2 i)
1<<i ; This does a binary left shift by I places - so only works if I<31 (if 31 you get a negative answer because integers are signed 32-bit integers in SKILL
