Dichotomous object variables   
If you want to tabulate some grouping variables with a group of
dichotomous variables (one at a time) then a lot of space can be
saved by using IVARIABLES specification for these dichotomous
variables, e.g.

GROUPING=CAR
IVARIABLES=Featr1,Featr2,Featr3,Featr4,Featr5,Featr6
Featr4=2  Featr5=10,99  Featr6=USA
By default the program assumes that the interesting value of a
dichotomous object variable is 1, which is tabulated against
all othe values considered as one group. Only the results for
that interesting group are given. The user may define other
interesting values by the following form:

<variable name>=<min,max> or <string> 

If necessary the maximum number of object variables may be
altered by MAXVBLS=<new limit> definition.

Note! The VARIABLES and IVARIABLES specifications may not be
used at the same time.
