Recoding into binary variables multiple responses done by choice vars.
-----------------------------------------------------------------------

    ^zb_qrm^ rootch nch rootnew nnew 

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

^zb_qrm^ generates 'nnew' new binary variables according to the
code of the 'rootexist' variables. Usually multiple
choices are registred in variables representing first choice,
second choice etc. The name of these variables are assumed to be 
numbered from 1 to the maximum number of choices. The 'rootch' 
parameter specifies the root-string in the names and the names
are 'rootch1' 'rootch2'. The same naming convention exists for
the new binary variables having the root string 'rootnew' and
are numbered from 1 to 'nnew'. The codes in the existing variables
must be the same. Missing values are allowed. The program zb_qrm 
print a frequency statistic of each code and one of the 
combinations of all codes.


Remarks
--------


Parameters (no one is optional)
-----------

rootch :  Root string of 7 or fever characters which is the rootname 
          of the input vars.
		  
nch :     Number of input variables or choices.

rootnew : Root string of 7 or fever characters which is the rootname
          of the output vars.
		  
nnew :    Number of codes in the input variables and
          number of output variables

Beside the new numbered output variable a new variable having
only the 'rootnew' name will be created representing
all combinations of the output variables.


Example
--------

    . ^zb_qrm test 6 testb 15^
	   
	   This will analyse the variables test1-test6 and create
	   testb1-testb15
