For non-OOP languages, a custom routine is a function, procedure, or subroutine and for pure OOP languages, a custom routine is a class method. Hybrid languages (both non-OOP and OOP) combine both.

ASP Classic:   Sub, Function ASP Classic is a non-OOP language with some OOP features. It offers both Subs and Functions. A Sub does not return a value while a Function does. When Subs and Functions are used in a defined class, they become the methods of the class. Syntax Example: Sub SayHello(ByVal pName)   Response.Write "Hello " + pName + "!<br>" End Sub   Function Add(ByRef pN1, ByRef pN2)   Add = pN1 + pN2 End Function  ASP Classic Custom Routines (Sub, Function)

VB Classic:   Sub, Function VB Classic is a non-OOP language with some OOP features. It offers both Subs and Functions. A Sub does not return a value while a Function does. When Subs and Functions are used in a class module, they become the methods of the class. Syntax Example: Sub DoSomething(ByVal pMessage As String)   MsgBox (pMessage) End Sub Function GetAge(ByRef pFullname As String) As Integer   GetAge = 7 End Function  VB Classic Custom Routines (Sub, Function)

Also known as embedded code where you embed another syntax language within the native code of the development environment you are using. The inline code can be compiled by the current development's compiler or by an external compiler.

Do not confuse with inlining which is a coding technique where custom routines are moved inline where the code is executed either by you, by a compiler directive, or automatically by the compiler.

General Info: Inline Routines

Instead of calling a routine, you move the code from the routine itself and expand it in place of the call. In addition to manual inlining, some languages support automatic inlining where the compiler or some other pre-compiler decides when to inline a code routine. Also, some languages allow for developer defined inlining where the developer can suggest and/or force the inlining of a code routine. Inlining can optimize your code for speed by saving a call and return, and parameter management.

Does it support inlining? If so, does it support developer defined inlining? Does it support automatic inlining? Both?

Types of overloading include method overloading and operator overloading.

Method Overloading is where different functions with the same name are invoked based on the data types of the parameters passed or the number of parameters. Method overloading is a type of polymorphism and is also known as Parametric Polymorphism.

Operater Overloading allows an operator to behave differently based on the types of values used. For example, in some languages the + operator is used both to add numbers and to concatenate strings. Custom operator overloading is sometimes referred to as ad-hoc polymorphism.

ASP Classic:   Not Supported ASP Classic does not support any type of overloading. Operator - No. Method - No. Some developers like to pass in an array and then handle the array for a pseudo technique. Although not overloading, it's useful.  ASP Classic Overloading (Not Supported)	VB Classic:   Not Supported Developer defined overloading in VB Classic: Operator - No Method - No  VB Classic Overloading (Not Supported)
