Function/Subroutine Documentation

subroutine status	(		LUNIT,
			LUN,
			IL,
			IM
	)

This subroutine checks whether a specified Fortran logical unit number is currently connected to the BUFRLIB software.

If the unit number is already connected, then the subroutine returns information about the associated file. Otherwise, it returns the next available internal I/O stream index that could be used to connect the associated file to the software via a subsequent call to subroutine wtstat().

Parameters

[in]	LUNIT	– integer: Fortran logical unit number for BUFR file
[out]	LUN	– integer: Internal I/O stream index associated with LUNIT 0 = LUNIT is not already connected to the software, and there is no remaining internal space available that could be used to connect it
[out]	IL	– integer: File status 0 = LUNIT is not already connected to the software, but LUN contains a new internal I/O stream index that could be used to connect it via a subsequent call to subroutine wtstat() 1 = LUNIT is already connected to the software for output operations (i.e. writing/encoding BUFR) -1 = LUNIT is already connected to the software for input operations (i.e. reading/decoding BUFR)
[out]	IM	– integer: Message status, indicating whether there is already a message open within internal arrays for LUNIT 0 = No 1 = Yes

Date	Programmer	Comments
1994-01-06	J. Woollen	Original author
1996-12-11	J. Woollen	Fixed a long standing bug which occurs in unusual situations, very low impact
1998-07-08	J. Woollen	Replaced call to Cray library routine ABORT with call to new internal routine bort()
1999-11-18	J. Woollen	The number of BUFR files which can be opened at one time increased from 10 to 32
