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...
Have a great day
Ara
