In that case you would need the form action to be the script, and submit another field which the script uses to find the right subroutine. You could use a hidden field. But a nice way to do it IMHO is with the submit button. Since the value field in a Submit button only gets submitted with the form when that particular button is pressed, you have the option of different buttons within the same form. For example, in the html:

<FORM ACTION="yourscript.pl" METHOD="POST">
<!-- insert other form inputs here -->
<INPUT TYPE="SUBMIT" NAME="Action" VALUE="Run Foo">
<INPUT TYPE="SUBMIT" NAME="Action" VALUE="Run Bar">
<INPUT TYPE="SUBMIT" NAME="Action" VALUE="Store Event">
</FORM>

Then in the script (in this example saved as yourscript.pl) you could have something like

use CGI qw/:standard/;

if (param('Action') and param('Action') eq 'Run Foo') {
    foo();
}
elsif (param('Action') and param('Action') eq 'Run Bar') {
    bar();
}
elsif (param('Action') and param('Action') eq 'Store Event') {
    store_event();
}
else {
    print
        header,
        start_html('Ack!'),
        h1 'you have to call this from the form!',
        end_html;
}
