variable
A variable is a symbol associated with an
Object or a
Method that can be either read or written.
Each variable must have a datatype. i.e.
String,
Integer, etc.
A variable can be public, private or local.
Only classes written in
Gambas can declare public variables.
A variable is faster to access (because it accesses memory directly for reading and writing its value) than a
Property, but you have no control on it.
In order to use a variable you must declare it either in the
beginning of the
Class or in the
beginning of the procedure.
In VB Variables can be declared "inside" the code.
Beware that variables whose datatype is
Object, any array, or any class, are initialized with
NULL.
You must initialize them with a real object created with the
NEW keyword before using them.
