Bob, why Options(*STRING) on inBuffer?  That option allows you to pass a
character expression, but when you do, the character expression always
gets copied to a temporary with a null following it.

If someone did pass a character field thinking it would get set by
fgets, all that would actually be set would be the compiler's internal
