Introduction to SR Programming Language

SR- Synchronizing Resources

SR Programming Language is used to write concurrent programming Language. The main part of languages constructs are resources and operations.Encapsulation of process and variable are resources and operation provides the basic mechanism for process interaction. It provides integration of the mechanism for invoking and servicing operation.

Example of SR Programming Language

In the given example it wills print the factorial of a number:

resource factorial()
   procedure fact(k: int) returns f: int
      if k < 0 -> f := -1
      [] k = 0 or k = 1 -> f := 1
      [] k > 1 -> f := k * fact(k-1)
      fi
   end fact

   var n: int
   writes("How many factorials? "); read(n)
   write()   # generate a linefeed, resulting in a blank line
   fa i := 1 to n ->
      write(i, "factorial is", fact(i))
   af
end factorial
