Sorry if I mischaracterized you view - I chose the phrase "I gather" with
the intent of expressing MY understanding/interpretation of your postings.
I guess I MISunderstood/MISinterpreted.
I chose "odd" for lack of a better term to describe code using a char* for
an array of ints.
I fully agree that the code is standards-compliant - otherwise I'd not care
one iota about warnings or no warnings.
