For 80 observations, I have information on 3 binary (0,1) variables.
I'd like to get a file containing all possible combinations
(80*80*80=512000). So, let's say I had
_n var1 var2 var3
1 a b c
2 d e f
and I need a data file that contains
1 a b c
2 a b f
3 a e c
4 a e f
5 d b c
6 d b f
7 d e c
8 d e f
How may this be accomplished?

I am not sure what you want. You have three binary variables (0,1),
yet you gave them the values (a,d), (b,e), and (c,f).
I can see 8 rather than 512000 possible combinations:
0 0 0
0 0 1
0 1 0
0 1 1
1 0 0
1 0 1
1 1 0
1 1 1
and that number is unrelated to any empirical findings.
But that is probably not what you are looking for.
