I think you are looking for Win32:API. With this module, you can do something like:

use Win32::API;
my $objDataControl = Win32::API->new("blpdatax", "<c prototype of func
+tion>");
my $bloomData = $objDataControl->Call();

You can do this for each API call you want to import into your script. Of course, this means you have to know what the C prototype of the API call you need looks like.

update
Forget about Win32::API. I did a little more digging on the Bloomberg API you are working with, and it looks like you are trying to access an ActiveX object, which can only by done thru Win32::OLE.
