Cool! Thanks! That's exactly what I was looking for: a simple pure Perl solution. Plus, it looks like you saved me a trip through time. :)

From ActiveState's documention on Win32::GetProcAddress :
Returns the address of a function inside a loaded library. The information about what you can do with this address has been lost in the mist of time. Use the Win32::API module instead of this deprecated function.

Now there's one concern in my mind. If I use Win32 to access the variables and Win32::API to access the functions, would the two modules load different instances of the dll? If so, I'll have another problem on my hands.

If I understand correctly, I suspect that I can follow your example and by using only the pack 'L!', $proc syntax of the last line to get the address of variables and functions. With that, I should be able to get any variable or function in my code to 'point' to a corresponding variable/function in the dll and would not necessarily need Win32::API. Then I don't have to worry about the possibility of my code accessing different instances of the dll.

If I get this all figured out, I'll be sure to post an update on what I did so that others can learn from my travels guided by your useful information.

Again, thanks for the help!
