No unfortunately it is not what I want.
I am just trying to have a table showing how many times a dummy is
released contemporaneously to each other dummy for each interval time
through my sample.
Thank you very much anyway.

If you have only four dummies then:
*** example begin***
gen d1d2d3d4 = D1*1000 + D2*100 + D3*10 + D4
tab d1d2d3d4
*** example end***
Might do what you want?

This is an example of my databse:
Date Time D1 D2 D3 D4
01/01/2008 8:00 1 0 0 1
01/01/2008 9:00 0 0 0 0
01/01/2008 10:00 0 1 1 0
..... ....... . . . .
For every day I have something similar to the above example with
dummy variables.
In the fist row (8:30) I have that two dummies happen at the same
time and also in the last row (10:00).
I want to construct a table, in which I have the number of times
( for each interval throughout my whole sample) I have that events
D1 and D4 happen together and D2 and D3 happen together and so on
for all
