sequencer_file_name_to_number_c

	status.i4.v = sequencer_file_name_to_number_c(sequencer_mode.i4.v,
						      file_name.i1a.r,
						      file_number.i4.r)

	This routine returns the Sequencer file number corresponding
	to a file name.

	sequencer_mode	Sequencer mode
	file_name	null terminated file name to search for
	file_number	returned corresponding file number

	This function returns ACNET status values as follows:

	OK			success
	CLIB_INVARG		invalid Sequencer mode
	CLIB_NO_SUCH		no matching file name was found
	SQL_xxx			error reading database information

	This function requires the following include files:

	ul_cbsaux_h:auxlib_misc_h, acnet_errors_h
