Corresponds to:

• the number of the current record in the data file.
• the number of the current record in the view or in the query (and not the number of the current record in the data file).
  Caution: Used on a HFSQL Classic view, this parameter does not correspond to the value of the H.NumRec variable.
• the hInvalidRecNum constant if there is no current record (position outside the data file).

HError returns more details about the problem.

Used on an Hyper File 5.5 view, HRecNum returns the number of the current record in the data file associated with the view.

Name of HFSQL data file, query or view used.
If this parameter is not specified, HRecNum will use the last data file used by the last HFSQL management function (function starting with "H").
