before:
snake DW s_size DUP(0)

now:
snake rw s_size

Now this line has a problem, please advice what can i do;

MOV DX, snake[0]

Note: I tried to look for some help in the HTML manual, but I think this is only a syntax problem.

Flatassembler uses the 'times' directive instead of DUP, see below:

Code:

snake: times s_size DW 0

is the same as,

Code:

snake dw s_size DUP(0)
