Greg (and others) .... my apology for the typo (one of them was a double
quote, not single) which 'unbalanced' the quotes.
However, you are wrong about second assignbment statement; what I posted
was correct. If you think about the general principles of assignment
statements, when, in any computer language I know, code an assignment
statement of the form:
A = B
... then the value of B is asigned to A (which therefore has to be a
variable). One cannot 'assign a value' to '10280079' !!
Apologies again for the quote typo.
Kind Regards
John
