Variables can be of the type integer, double, boolean and string. All variables have to be defined at the beginning of the code. Variables are defined with the Dim statement, constants with the Const statement.
Examples:dim i as integer
dim t as text
const parselength=1024
Do not use any reserved word for variable names or you will have a severe parsing error. Reserved words are the names of the operators, the control structures and of all built-in functions.
Variable names are not case-sensitive.
Variables are automatically initialized (integer and double: 0, string: ""; boolean: false).
