This is one of the first things I tried to do in C++ too, but I did this
instead:
	class keys
		{
		public:
		const ENTER = 0x13;
		// ...
		};

	class program : keys
		{
		public:
			int function(void) { return ENTER; }
		// ...
		}

But I was rewarded with a "not yet implemented" error message :-/

I would hope that static const's are now "implemented" with cfront 2.0.

[btw, I found your syntax for the "program" class method 'function' a bit
 cryptic -- hope I didn't misread what you wanted here.]
