Introduction
In B4P, every variable stored contains following information which help to describe the data stored and the variable form:
| Attribute | Description |
|---|---|
| Variable Name | A string of choice. Exception: Array members have no names as they are just numbered |
| Value | Stored value (Base Variable) |
| Data Type | Variables can assume any Data Types and subtypes such as string, numeral, etc. |
| Variable Form | Distinguishes whether the variable is a simple variable, an array or a structure, or a simple variable containing zero members |
| Members | Contains all member variables (in arrays and structures). Every member is treated like an individual variable, too. |
| Member count | Number of existing members (0 for simple variables) |
| Protection Setting | Applies rules on accessing and/or modifying these variables, e.g. read-only, prevent deleting, etc. See function protect() |
| Locked | Variables may be temporarily locked during the time while an assignment on that variable is executed or a reference is pointing on this variable. Locked variables cannot be deleted. |
