Hi, in a given c program where you have

myvar = sumR(char * arg1, int arg2)

sumR is a function in an assembly .s file. I have done all the calculations, but I have no idea how to return the value to the calling c program.

Any ideas?

Thanks so much.

Usually the value is returned in R0. So in your sumR, after you do your stuff, place what you want myvar to equal in R0

Thanks. If you don't mind one more, how do you print the contents of a register which contains an int.
