Arx scripts know three basic data types: int, real and text. Variables can be either global (shared between all entities) or entity-specific. There are also special system variables than can only be read. The variable type is defined by the first character of the variable name.

Char Byte Scope Type
# 0x23 global int
& 0x26 global real
$ 0x24 global text
§ 0xA7 entity int
@ 0x40 entity real
£ 0xA3 entity text
^ 0x5E system (mixed)

While variables in Arx scripts are typed, there are no type restrictions for where variables are used: the types are converted automatically.
