Hi List,

I have a file with all the variable like this:

data list free/ id  q1.1 q1.2 q1.3 q2.1 q2.2.
begin data
001 0 0 1 1 0
002 1 0 0 1 0
003 0 1 0 0 1
004 0 0 1 0 1
end data.

I would have a file like this:

data list free/ id  q1 q2
begin data
001 3 1
002 1 1
003 2 2
004 3 2
end data.

Obviously, I can do this with a lot of if-statements, but I'd like to know
if there is a faster way.

Thanks in advance,
Arnaldo.
