Hi there :)
I'm just doing a basic switch/case like this:
static final int PONG = 1;
...
input.msgcode = PONG;
...
switch(input.msgcode)
{
case PONG:
....
break;
}
If I do something like this I get the following error:
"server.d:189: Error: case must be a string or an integral constant, not PONG"
What do I do?
Cheers!

PONG is not constant. Use 'const' to declare a constant: const int PONG = 1; ''final' is ignored in your example. It is used to make public member functions final: http://www.digitalmars.com/d/function.html
