I am an old programmer so I have a lot of good assemby routines from the old DOS ages. Now, however, I have to develop in Windows environments (95, 98, NT) and I actually do it. My old routines would even be welcome while I write programs to these new platforms. My question would be what the conditions are to translate old assembly sources to DLL-s which could be used by Windows EXE-s.
If possibile please suggest a good development environment for this task.
