Interface `query`

$\begin{boxedminipage}{\textwidth} \begin{verbatim}call query(this[,frame])\end{verbatim} \end{boxedminipage}$

Query the CInOutput stream to fill in values of n_frame, n_atom, n_property etc. Called once automatically by read(), but if the structure of the XYZ file changes between frames you need to call it again each time.

this -- type(CInOutput), intent(inout)

frame -- integer, optional, intent(in)
