Why do this not work:

Global l:Long
l=$8000000000000000
Print l

OK.Bruce i have another question to you

I have a long in c like this

	long l;
	l=MACAddress[0]*0x1000000000000+MACAddress[1]*0x100000000+MACAddress[2]*0x1000000+MACAddress[3]*0x10000+MACAddress[4]*0x100+MACAddress[5]*0x1;
return l;

but it returns a 0

If you want to define a long as a constant you have to put :Long on the end otherwise it chops off the top 32 bits and converts it to an integer.

For 0x1000000000000, surely you need to use a "long long", unless your code is 64bit (where I guess a long is 8 bytes?).
Generally in C, a long is the same size as an int these days - at least in 32bit land.

And once you are in the realms of "long long", then the fun with BlitzMax will really begin...
