  I have a situation in which I would like to do a 'show route <x>' and would like to perform a test on the outgoing interface returned for the active route.

The test I would like to perform is whether the subinterface of the outgoing interface is either even or odd.  So I suppose two questions would be, would Slax convert a string into a number depending on the context of the operation being performed on it...and is there an elegent (or any) way to test for evenness or oddness?

SLAX does automatically convert strings into numbers as required (or it tries to at least). The following code is an example of how you could achieve your objective. A mod result of 1 indicates it is odd, 0 indicates it is even:

        var $interface-name-1 = "ge-0/0/1";
        var $interface-name-2 = "ge-0/1/2";
        
        var $digits-1 = translate( substring-after( $interface-name-1, "-" ), "/", "" );
        var $digits-2 = translate( substring-after( $interface-name-2, "-" ), "/", "" );
        
        <output> $digits-1 mod 2;
        <output> $digits-2 mod 2;

Thanks for the reply, I haven't had time to implement this, but it looks like it will do the trick.
