If you tell us what the ultimate goal is, you may get better advice.

Subject: st: convert decimal number in binary format

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
