returning values from assembly to c

You'll need to assign it to a 'C' variable.

See: http://www.keil.com/forum/docs/thread9558.asp

But please pay attention to all the issues raised there about inline assembler - unless you have a really compelling reason to do it, and unless you really understand what's going on, just don't do it!.

Write a separate assembler module instead, and Call it from 'C' - then you can use the documented function call & return conventions described in the C51 Manual
