[Serusers] if routeXX fails..

[Marian Dumitru]

Hi Matt,

If you return from the route via "break", the route will return always 
true. The trick is to avoid the break instruction for leaving the route 
and to have as last instruction something which returns false for sure.
Like this stupid example:

route[x] {
	resetflag(4);
	isflagset(4);
}

route[y] {
	if ( route(x) ) {
	.......
	} else {
	.......
	}
}

route x will be evaluated as false all the time due to isflagset which 
returns false all the time.

Best regards,
Marian
