Custom Routines (C++ and ObjectPAL Cross Reference Guide)

C++ is a hybrid language and as such offers global functions and class methods. A function must come before it's usage or you can prototype the function.

void sayHello(string pName) {
  cout << "Hello " + pName + "\n";
};

int add(int p1, int p2) {
  int result;

  result = p1 + p2;
  return result;
};

 C++ Custom Routines

ObjectPAL is a non-OOP language (an object-based language) that offers custom methods and custom procedures. When you create a custom method, you associate it with an existing object like a button, form, or library.

When calling a custom method or procedure that has a by reference parameter (uses var), then you cannot use a literal value. this is different than in many other languages which do allow you to pass literals by reference.

method sayHello(var pName String)
 msgInfo("", "Hello " + pName)
endMethod
 

method add(p1 Number, p2 Number) Number
 Return p1 + p2
endMethod
