Ok, now I've got something like this, but it still doesn't works and have the same errors like earlier.

Code:
#!/bin/bash

echo "Max length of line: "
read n

awk -v var="$n" '
    
    { MAX = var };
    {
        LEN = length(\$0);
        
        if(LEN % MAX != 0){
            N = (LEN - (LEN % MAX)) / MAX + 1;
        };
        
        if(LEN % MAX == 0){
            N = LEN / MAX;
        };
        
        for(x = 0; x < N; x++){
            POS = ((x*MAX) + 1);
            STR = substr(\$0, POS, MAX);
            {print STR};
        }
    }
' data

As someone else noted earlier, remove the backslash.

Also, instead of setting MAX=var, why not just set -v MAX=... ?
