Usually you give your submit button a value and a name:

<input type="submit" name="action" value="Search">
<input type="submit" name="action" value="Logout">
[download]

and if you

use CGI;
[download]

you can then test for what action to do:

if (param("action") eq "Search") {
   # ...
}
# ...
[download]

Please take into account that this comes from the back of my head and I have not been doing CGIs for more than a year now; still it should be correct.
