Author

Date

1994-01-06

Parameters

[in]	LUNIT	– integer: Fortran logical unit number for BUFR file
[out]	SUBSET	– character*8: Table A mnemonic for type of data subset that was read (see DX BUFR Tables for further information about Table A mnemonics)
[out]	IDATE	– integer: Date-time stored within Section 1 of BUFR message containing data subset that was read, in format of either YYMMDDHH or YYYYMMDDHH, depending on the most recent call to subroutine datelen()

Returns

ireadns – integer:

• 0 = new BUFR data subset was successfully read into internal arrays
• -1 = there are no more BUFR data subsets in the file connected to logical unit LUNIT

Remarks

• The use of this function allows the return code from readns() to be used as the target variable within an iterative program loop.
