Barry, I agree on most issues ... have experienced the hardship of thinking arrays ... has cost me a lot of time...
Fortunatley (I think) I have lost the limited C programming I could do ... actually I used turbo Pascal because it was less forgiving than C / C++ ... I know C++ had improved a lot since .. the old days... so I don't even consider a DLL task now. The advantages I see for a DLL (other than hiding your code) is to group common routines AND faster execution under some conditions. I have some very slow code that becomes unusable in real time...
