====== Record Count ======

A special call is available for BFSs to return a count of the records in a file.  This call was designed for filing systems such as Linear Hash ([[system_bfses_in_openinsight|RTP57]]) that maintain a record count directly in the file. This call is available only through the system subroutine [[get_reccount|GET.RECCOUNT]] (or directly).

If the filing system is not able to fulfill the request for a record count, it will return a status value of zero. This value is in turn passed back via the second argument of GET.RECCOUNT as a "valid" flag.
