Hi Monks,

Let’s say I’m doing this in my main script: 

require mydir::mymod123;
$result = mydir::mymod123::mysub();

[download]
And the module looks something like this: 
package mydir::mymod123;
sub mysub
{
  ...etc...
  return $x;
}
1;

[download]
The above works, but the "123" part could be any of hundreds or thousands of numbers, so I’ll store that number in $modno, and I can "require" the module like this: 
    $modno = 123;   # Just for simplicity.  Actually this number will 
+come from a database.
    require "mydir/mymod$modno.pm";

[download]
That seems to work, but how can I call mysub() now?

I’d like to avoid using a dispatch table please, because it could get very long, and I don’t want to have to modify the code each time a new module is added to mydir.

Also, if each module will always contain only 1 sub, do they need to have a sub at all? If not, how can they be written & called without a sub?

Thanks.
