Those are just the port numbers I use (as expressed by X & VNC), Red Hat 
chose this method around RHL 7.x.

The expression VNCSERVERARGS[66] is how bash addresses arrays.

I think the limit's 99, maybe 100. ":66" translates to TCP port 5966, 
but one can also access vnc by HTTP to TCP ports 100 less, so 5866 in 
this case.
