Does this imply that software in ROM does not need to be copied (in the legal sense) when it's run, but cashing the ROM would consitute a copy? Or does copying each byte in turn into an internal processor register count as a 'copy'.. And what is the difference between copying a program (from disk, say) into a computer's memory, and copying part of a book into _my_ memory (e.g. learning something from a book). For that matter, what is the difference between a computer executing a program and me 'executing' a recipe from a cookery book? -tony
