Common Bug 2

	SUBROUTINE delphi(dphi)
$$INCLUDE 'C$INC:BCS.INC'
$$INCLUDE 'YBOS$LIBRARY:ERRCOD.INC'
	REAL dphi	! difference in phi's
	REAL phi1	! phi of muon
	REAL phi2	! phi of electron
C.................................
	dphi = -9999.
	status = blocat(iw,'MUON',1,ind,indmuo)
	IF(status .NE. yesucc) RETURN
	status = blocat(iw,'ELEC',1,ind,indele)
	IF(status .NE. yesucc) RETURN
	phi1 = rw(indmuo+15)
	phi2 = rw(indele+5)
	dphi = ABS(phi1-phi2)
	RETURN
	END

This routine will probably crash.

Why?
