# Enum Statement [VBA]

Define enumerations or non UNO constant groups. An enumeration is a value list that facilitates programming and eases code logic review.

This constant, function or object is enabled with the statement Option VBASupport 1 placed before the executable program code in a module.

### Syntax:

           Enum list_name
               ' Object Statement block
           End Enum ' list_name

## Parameters:

Within a given enumeration, fit together values that logically relate to one another.

### Example:

           Option VBASupport 1
           Private Enum _WindowManager
               W1ND0WS = 1 ' Windows
               OS2PM = 2 ' OS/2 Presentation Manager
               MACINTOSH = 3 ' Macintosh
               MOTIF = 4 ' Motif Window Manager / Unix-like
               OPENLOOK = 5 ' Open Look / Unix-like
           End Enum
           Public Function WindowManager() As Object
               WindowManager = _WindowManager
           End Function ' <library>.<module>.WindowManager.XXX

Enumerated values are rendered to Long datatype. Basic functions are public accessors to enumerations. Enumeration names and value names must be unique within a library and across modules.

## Usage:

Display WindowManager grouped constant values:

           Dim winMgr As Object : winMgr = <library>.<module>.WindowManager
           With winMgr
               Print .MACINTOSH, .MOTIF, .OPENLOOK, .OS2PM, .W1ND0WS
           End With

Enumerations can be extended to other data types using Type statement definitions. Calling Python Scripts from Basic illustrates that mechanism.
