Bash syntax will not have the min/max behaviour though unless you use a 
kind of modulo which will make it complex.

ie. normally you would do that with: x = (x + 1) mod 4, or x = (x - 1 + 
4) mod 4.

although I'm not sure a standard "round robin" function like that would 
be meaningful but who knows.

so the " arithmetic --set fred --min 2 -- max 10 "1" "+" "2" "

will come down to

fred=$(( (((fred-2) + 1) % 8) + 2 )) -- I assume. Or if you still had 
those min/max functions it'd come down to ?

arithmetic --set fred --min 2 --max 10 $(( fred + 1 ))     ?
