C ABSTRACT: 
C 
C ISPTH IS A LOGICAL FUNCTION THAT DETERMINES WHETHER A 
C ITEM IS A PATH OF A SET.
C 
C CALLING SEQUENCE: 
C 
C      CALL ISPTH(IBASE,DSNUM,DINUM,ISTAT)
C 
C      WHERE: 
C 
C      IBASE
C      IS THE BSE PARAMETER FOR THE DATA BASE 
C 
C      DSNUM
C      IS THE DATA SET NUMBER 
C 
C      DINUM
C      IS THE ITEM NUMBER 
C 
C      ISTAT
C      IS A TEN WORD INTEGER ARRAY USED FOR ERROR RETURNS 
C      FROM DBMS.  ISTAT IS ZERO WHEN THERE ARE NO DBMS ERRORS
C      ELSE ISTAT CONTAINS THE ERROR CODE FROM DBMS.
C 
C 
C ON EXIT:
C 
C     TRUE - DINUM IS A PATH OF DSNUM 
C     FALSE -  DINUM IS NOT A PATH OF DSNUM
