Introduction to Service parts

The EGL Service part is like a program that has multiple entry points.

Here is an example:

Service MyService{}

   // variables and constants can be here

   function calculate(myScore INT[]) returns (BIN (4,2)) 

      numberOfScores, i, mySum INT;
      numberOfScores = myScore.getSize();
      	
      for (i from 1 to numberOfScores by 1)
         mySum = myScore[i] + mySum;	       
      end
    	      
      return(mySum/numberOfScores);
   end

   // other functions are here

end

The function calculate receives an array of integers and then calculates and returns the average. The service can make multiple functions available to service requesters.
