Program part in EGL source format

You declare a program part in an EGL file, which is described in EGL source format. When you write that file, do as follows:

• Include only those parts that are used exclusively by the program

• Do not include other primary parts (dataTable, library, program, or pageHandler)

The next example shows a called program part with two embedded functions, along with a stand-alone function and a stand-alone record part:

  Program myProgram type basicProgram (employeeNum INT)
  { 
    includeReferencedFunctions 
  }

    // program-global variables
      employees record_ws;
      employeeName char(20);


    // a required embedded function
    Function main() 
      // initialize employee names
      recd_init();

      // get the correct employee name
      // based on the employeeNum passed
      employeeName = getEmployeeName(employeeNum);
    end

    // another embedded function
    Function recd_init()
      employees.name[1] = "Employee 1";
      employees.name[2] = "Employee 2";
    end
  end

  // stand-alone function
  Function getEmployeeName(employeeNum INT) returns (CHAR(20))

    // local variable
    index BIN(4);
    index = 2;
    if (employeeNum > index)
      return("Error");
    else
      return(employees.name[employeeNum]);
    end

  end

  // record part that acts as a typeDef for employees
  Record record_ws type basicRecord
    10 name CHAR(20)[2];
  end
