Thanks, works both perfect:
    
    
    Run

var i = 0 i = ((i - 1) + 4) mod 4 echo i i = ((i - 1) + 4) mod 4 echo i i = ((i 
- 1) + 4) mod 4 echo i i = ((i - 1) + 4) mod 4 echo i i = ((i - 1) + 4) mod 4 
echo i echo "\-----" i = 0 i = (i - 1) and 3 echo i i = (i - 1) and 3 echo i i 
= (i - 1) and 3 echo i i = (i - 1) and 3 echo i i = (i - 1) and 3 echo i i = (i 
- 1) and 3 echo i
