OK I hope I am not tredding on several toes. But I have released/sold 5 commercial applications on 64 bit windows assembler to 4 pretty high profile US/EU Semiconductor companies mostly involved in massive data applications. Now I am worried about legal issues. So far they have been ML64-ish, wee bit modified, recently looking at HJWASM but not released anything yet on HJWASM. What is the situation with commercial apps on ML64, HJWASM etc - totallay confused. I have already modified HJWASM but still not sure. Arrgghh wish it was BBC basic .......
