How do I get REGISTER variables recognized by the Microsoft Compiler??

[markcm]

Hi,

I need to get some legacy C++ (Borland) code to compile under the Microsoft Visual C++ compiler. However, the Microsoft compiler complains that the "REGISTER" variables (i.e. the _AH, _AL and _AX variables) are not recognized as registers by the Microsoft compiler. Does anyone know how to get around this problem??

An example of the C++ code that is failing compile follows:

_AH = enhancedKeyBrd;
geninterrupt(0x16);
asciiScan = _AX;
return (int) _AL;

THANKS,
Mark Michaud.
