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.

Perl:   sub Perl uses subs and parameters are referenced in a special array. All arguments passed to a subroutine are stored in a special @_ array. To retrieve the arguments, you have to look inside the array and extract them. Syntax Example: sub sayHello {  my ($pName) = $_[0];  print("Hello $pName!"); } sub add {  my ($p1) = $_[0];  my ($p2) = $_[1];  return $p1 + $p2; }  Perl Custom Routines (sub)

Access VBA:   Sub, Function Access VBA 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 SayHello(ByVal pName As String)   MsgBox ("Hello " & pName) End Sub Function Add(pN1 As Integer, pN2 As Integer) As Integer   Add = pN1 + pN2 End Function  Access VBA 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.

Perl:  Perl Operator - Yes Method -  Perl Overloading	Access VBA:   Not Supported Some developers like to pass in an array and then handle the array for a pseudo technique but that's not really overloading.
