AFAIK you are supposed to be able to use PRINT statements and have
the results output as text rather than generating a graph. I've never
tried with with a CDEF though (as opposed to printing a single value
VDEF) so I don't know if that works.
Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed
author Gladys Hobson. Novels - poetry - short stories - ideal as
Christmas stocking fillers. Some available as e-books.
