This piece of code doesn't do what you probably think it does.

Although it works here, y is a string variable and not a numeric variable.

If you add some extra echo statements you can see:

> y=0
> arg[$y]="hello"
> y=$y+1
echo $y
> arg[$y]="dan"

The content of $y is the string '0+1'.

The following assignment to arg[] correctly evaluates the 0+1, so it works
_in this case_, but you should probably be using _let_ :

let y=0

instead of

y=0

and elsewhere where you want to ensure that y is a numeric variable.
