: For example, the following code:

:   _BX = 0x0010;
:   _AL = 0x00;

   this is not supported by VC++ and other compilers as well.
The best way to rewrite this is use external assembler function.  This is
one of reason why I never use inline assembler in my C code.

:   if (_AL == 0)
:     return 0;

: compiles in Borland, but I get an error "undeclared variable" message
: w/ Microsoft.
: I checked Microsoft's Knowledge base but found nothing.
: Any help would be appreciated.
: Thanks.
