I shall modify some code written for the Metalink assembler for someone who will possibly do some minor maintenance himself. I am using the full version of the Keil tools and would like to work on the above with those. Since the coding efforts in the other end is about 10 lines per year suggesting the purchase of a full Keil is ridiculous - especially since the metalink works. Finally the question: will a program assembled and linked on the full version of the Keil toos be identical if assembled and linked by the eval version. Erik
