Keil MicroVision is new to me and I cannot get the variables in one function to be global because there is no "PUBLIC" command. How do I make it so a variable can be changed by any function. BTW I'm programming in C#. Any help is much appreciated.

You have absolutely no chance whatsoever of getting that to run on an 80251 - let alone an 8051. It doesn't even support ARM, so far as I know.
"Keil C compilers are based on C90. [Keil] added some language extensions as practical concessions to the architectural peculiarities of the microcontrollers [they] support and the needs of embedded systems programmers." http://www.keil.com/support/docs/1893.htm
That certainly doesn't include anything to do with C#, .NET, or even Windows!
