A (literal) number is required. To get a number

Ah, thanks Carl. This had been bugging me today. You know, I thought of
trying what you suggest , but didn't know how to "use the PV operator to
evaluate the concatenation each time." I thought I'd be trapped in the
problem of the program trying to write its own code on the fly.
Of course, you could reach the same result with a more conventional
XS parse.
Yes, I thought the VA@ way might be faster--do you have any opinion on
that, or do I need to run timing tests?

Much appreciated,
Harry
