[Gambas-user] Val function changed behaviour, porting gambas2 to gambas3

[Rolf-Werner Eilert]

The new behaviour of val() drove me nuts when it appeared first ;) I had 
used it in so many places, and all over my code. Sometimes it lasts for 
weeks until your program hits this place, and AGAIN val() Arrgh... :)

So in most cases, I ended up either checking for null before (somewhat 
roundabout) or just using CInt() instead.
