Hi, I have to write a script to do FTP file transfers that must run on Windows and Unix. For Windows, I will be using the Win32::Internet module and for Unix, I will be using the Net::FTP module. I have thought of several areas in which I might run into problems due to trying to get something to work transparently on both architectures and would appreciate any input into these situations as well as any I haven't thought of.

Creating an "FTPSession" Object for the Right Architecture at Runtime

This was discussed in a previous thread: Calling a class constructor as a function on input arguments

Trying to Include Modules Which Don't Exist for An Architecture

I think I have this one handled. I simply check $^O and do a run-time require as opposed to a compile-time use and thus only the modules existing for a particular architecture will be loaded on that architecture.

Code Will Have References to Variables and Functions (keywords) of the Modules for the Other OS

As I typed, I realized that one way to handle this is to move each arch's code into a different module and require the arch-dependent modules just as I do Win32::Internet and Net::FTP.

That being said, would there be compile-time errors if I used a single monolithic code body and made references to keywords of an unloaded module even if the code is never executed at runtime?
