MPLAB is written with Borland C++ 4.50 I talked with a friend who had written with BC4.50. He said me that he had problems when more than 1 BC program is using system DLL at same time. I have never written program with BC and have no opinion. Anyway, I am just now downloading something and am writing this letter and others but don't think to run MPLAB until the whole file comes to me. Ivan Cenov okto7@botev.ttm.bg
