I have an old version of c51 where I develop an application. I want to use a newer version of this compiler (c51), I want my old version to compile in the new version of c51. How can I make this work? Thanks!
"*** ERROR: CAN'T OPEN FILE 'avion3'" This probably means that the file either doesn't exist at all, or is not in the location specified or assumed. Given that you are also having problems with your Linker command line, probably the file doesn't exist at all because you haven't managed to get the Linker to create it yet! "I used de command OHS51 and with that command the compiler say that isn't a valid command" It wouldn't be the Compiler that said that - it would be your operating system. "so I changed for BL51" Yes, that is the correct name for the current Linker. "the program enter in a never end loop" You need to check that the complete command line is valid for BL51. Here is the Manual: http://www.keil.com/support/man/docs/bl51/ "I don't know how to rewrite the ".bat", any idea?" BAT files are pretty simple things - basically just a sequence of commnd lines. See a standard PC reference book.
