Function/Subroutine Documentation

subroutine ufbcnt	(		LUNIT,
			KMSG,
			KSUB
	)

This subroutine returns the current location of the file pointer within a BUFR file, in terms of a message number counting from the beginning of the file, and a data subset number counting from the beginning of that message.

Parameters

[in]	LUNIT	– integer: Fortran logical unit number for BUFR file
[out]	KMSG	– integer: Ordinal number of current message, counting from the beginning of the BUFR file, but not counting any messages which contain DX BUFR tables information
[out]	KSUB	– integer: Ordinal number of current data subset within (KMSG)th message, counting from the beginning of the message

Remarks

• Logical unit LUNIT should have already been opened via a previous call to subroutine openbf(). If LUNIT was opened for input operations, then KMSG is incremented with each call to any of the message-reading subroutines, and KSUB is incremented with each call to any of the subset-reading subroutines for that message. Otherwise, if LUNIT was opened for output operations, then KMSG is incremented with each call to any of the message-writing subroutines, and KSUB is incremented with each call to any of the subset-writing subroutines for that message.
• The value returned for KMSG does not include any messages which contain DX BUFR tables information.
