Dear all,
I search an idea to create variables which represents all the possible pattern of responses to a set of binary variables, for example with 3 variables :

var1 var2 var3
0    0    0
0    0    1
0    1    0
0 1 1 1 0 0
1    0    1
1    1    0
1 1 1
I have searched a command to convert a decimal number in binary format (here the responses patterns represents the number from 0 to 7 in binary format) but I have not find any such command.

I have no simple idea to create such variables (I want to create a programme where the number of variables is not fixed and can be large).

Has someone an idea to help me ?
Best,
Jean-Benoit
