As many as you like... Until you run out of memory...

As many numbers as a long variable can hold.

I seem to remember seeing somewhere that a CString couldn't hold more than 32767 characters, but I have just tried adding 65536 and it was OK. Has anyone else seen this 'limit'? Perhaps it is a throw-back to 16-bit VC++, where the parameter to GetBuffer() was an int (therefore, a maximum of 32767).
