Hi Marc,
The problem with Microsoft COFF format is PB cannot use it because it has data types that cannot be handled in COFF format. Most compilers have their own format of object module and while a few can use each others, many cannot. I am like many people who have used a language for a long time, I have over 15 years of 32 bit PB code floating around on different machines and buried in different archives and its hard to keep track of it all where in MASM which I regularly use it has always been in library format ad much easier to keep track of large volumes of code over a long period of time.
