    Upgrade your tool chain to 32 bit.
    Rewrite the code you have in 16 bit.

    You can mix 16 and 32 bit in DOS, but only with a hell of a lot of excess baggage.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Thanks for your information.
    Change the BC31 setting, after select "Compile via assembler", the program can compile pass now.
