Hi mates, I'm new to FASM. I need to ask how can I swap the even letters of word "even" with the odd letters of word "odd"?
I started writing some code:
format PE GUI
entry start
bol dd "even"
start:
movzx ecx, byte ptr bol+4
ret

Memory operands are written with square brackets:

Code:

movzx cl, [bol + 4]

Note also that operand sizes are important.
