    ftver = tmp.Version;

Somehowm, tmp is an empty struct or object (that does have a field or property named Version) . Remember that if you have a structure name followed by a period followed by a field name, then you have structure expansion happening; if the struct existed and was a scalar struct then tmp.Version would give you a single output; if the struct was a struct array, tmp(1) to tmp(5) for example, then tmp.Version would expand to that many outputs as a comma separated listed. And likewise, if tmp is empty them tmp.Version expands to zero outputs.
