I disagree on this (which doesn't make it wrong!) because PRINT is
not doing any calculations and IMHO it should stay that way.  What
do others think please?

Another way of aproaching this problem is to allow an RPN string
everywhere a variable is allowed now, this wouldn't make the xPRINT
series an exception.
