Description
-----------

^dropoper^ drops all operator variables from the current data set.  An operator
variable is formally defined as any variable containing a period (_), such as 
^L_gnp^ and ^L2_gnp^ created by ^lag^, ^F_gnp^ and ^F2_gnp^ created by ^lead^, ^D_gnp^ and
^D2_gnp^ created by ^dif^, and ^G_gnp^ created by ^growth^.  It also includes compound
operator variables such as ^LD_gnp^, created by applying ^lag^ to the result of
^dif^.
