Custom Routines (Java and Corel Paradox Cross Reference Guide)

Because java is an OOP language, all custom routines belong to a specific class and are therefore referred to as methods.

All methods in Java must return something so even with procedures, you return a "void".

public void sayHello(String pName) {
  System.out.println("Hello" + pName);
}

 

public int add(int p1, int p2) {

  return p1 + p2;

}

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
