C ABSTRACT: 
C 
C LVCHK CHECKS TO SEE IF THERE IS A LEVEL BREAK, AND SETS THE L-ARRAY 
C ACCORDINGLY.
C 
C CALLING SEQUENCE: 
C 
C      CALL LVCHK(INDX,STRNG,LEN) 
C 
C        WHERE: 
C 
C           INDX
C           IS THE INDEX INTO THE T-ARRAY AND L-ARRAY 
C              T-ARRAY CONTAINS INDEX INTO THE LIST-ARRAY 
C              L-ARRAY INDICATES LEVEL BREAKS 
C                  -1 INDICATES NO BREAK
C                   0 INDICATES BREAK 
C              LIST-ARRAY CONTAINS GOOD INFORMATION ABOUT THE 
C                   DBMS BUFFER, (ITEM NUMBER, ITEM TYPE, ITEM
C                   LENGTH, # ELEMENTS, OFFSET INTO DBMS BUFFER,
C                   A FLAG INDICATING WHETHER IT IS A SORT ITEM OR NOT) 
C 
C 
C 
C           STRNG 
C           IS THE BUFFER IN WHICH THE CURRENT LEVEL'S STRING 
C           IS PLACED.
C 
C           LEN 
C           IS THE LEVELS CURRENT LENGTH
C 
C  ON EXIT: 
C 
C           STRNG - CONTAINS CURRENT LEVEL BREAK STRING 
C           LEN   - CONTAINS LENGTH OF CURRENT STRING 
C           L-ARRAY ENTRY IS SET TO ZERO IF THE STRING CHANGED
