Function/Subroutine Documentation

function iupvs01	(		LUNIT,
		character*(*)	S01MNEM
	)

This function returns a specified value from within Section 0 or Section 1 of a BUFR message.

This function will work on any BUFR message encoded using BUFR edition 2, 3, or 4. It is similar to function iupbs01(), except that iupbs01() operates on a BUFR message passed in via a memory array, whereas this function operates on the BUFR message that was read into internal arrays via the most recent call to any of the other message-reading subroutines for a specified Fortran logical unit.

Parameters

[in]	LUNIT	- integer: Fortran logical unit number for BUFR file
[in]	S01MNEM	- character*(*): Value to be read from Section 0 or Section 1 of BUFR message in internal arrays for LUNIT 'LENM' = Length (in bytes) of BUFR message 'LEN0' = Length (in bytes) of Section 0 'LEN1' = Length (in bytes) of Section 1 'BEN' = BUFR edition number 'BMT' = BUFR master table 'OGCE' = Originating center 'GSES' = Originating subcenter 'USN' = Update sequence number 'ISC2' = Flag indicating absence/presence of (optional) Section 2 in BUFR message: 0 = Section 2 absent 1 = Section 2 present 'MTYP' = Data category 'MSBTI' = Data subcategory (international) 'MSBT' = Data subcategory (local) 'MTV' = Version number of master table 'MTVL' = Version number of local tables 'YCEN' = Year of century (1-100) 'CENT' = Century (e.g., 20 for years 1901-2000, 21 for years 2001-2100) 'YEAR' = Year (4-digit) 'MNTH' = Month 'DAYS' = Day 'HOUR' = Hour 'MINU' = Minute 'SECO' = Second

Returns

iupvs01 - integer: Value corresponding to S01MNEM

• -1 = S01MNEM was invalid for the edition of BUFR message in internal arrays for LUNIT, or some other error occurred

Remarks

• Values corresponding to S01MNEM = 'GSES' can only be read from BUFR messages encoded using BUFR edition 3 or 4.
• Values corresponding to S01MNEM = 'YCEN' or 'CENT' can only be read from BUFR messages encoded using BUFR edition 2 or 3.
• When reading from BUFR messages encoded using BUFR edition 2 or 3, values corresponding to S01MNEM = 'YEAR' will be calculated internally using the values for 'YCEN' and 'CENT', or inferred using a windowing technique
• Values corresponding to S01MNEM = 'SECO' or 'MSBTI' can only be read from BUFR messages encoded using BUFR edition 4.
