	)

THIS FUNCTION SEARCHES A "WINDOW" (SEE BELOW REMARKS) FOR AN ELEMENT IDENTIFIED IN THE USER STRING AS A CONDITIONAL NODE (I.E.

AN ELEMENT WHICH MUST MEET A CONDITION IN ORDER TO BE READ FROM OR WRITTEN TO A DATA SUBSET). IF A CONDITIONAL ELEMENT IS FOUND AND IT CONFORMS TO THE CONDITION, THEN THE INDEX OF THE ELEMENT WITHIN THE WINDOW IS RETURNED. OTHERWISE A VALUE OF ZERO IS RETURNED.

BENDER – ADDED REMARKS/BUFRLIB ROUTINE INTERDEPENDENCIES 2003-11-04 D. KEYSER – MAXJL (MAXIMUM NUMBER OF JUMP/LINK ENTRIES) INCREASED FROM 15000 TO 16000 (WAS IN VERIFICATION VERSION); UNIFIED/PORTABLE FOR WRF; ADDED DOCUMENTATION (INCLUDING HISTORY) (INCOMPLETE); OUTPUTS MORE COMPLETE DIAGNOSTIC INFO WHEN UNUSUAL THINGS HAPPEN 2009-04-21 J.

USAGE: INVCON (NC, LUN, INV1, INV2) INPUT ARGUMENT LIST: NC - INTEGER: CONDITION CODE: 1 = '=' (EQUAL) 2 = '!' (NOT EQUAL) 3 = '<' (LESS THAN) 4 = '>' (GREATER THAN) LUN - INTEGER: I/O STREAM INDEX INTO INTERNAL MEMORY ARRAYS INV1 - INTEGER: FIRST INDEX OF WINDOW TO SEARCH INV2 - INTEGER: LAST INDEX OF WINDOW TO SEARCH

OUTPUT ARGUMENT LIST: INVCON - INTEGER: INDEX WITHIN WINDOW OF CONDITIONAL NODE CONFORMING TO SPECIFIED CONDITION 0 = NONE FOUND
