1.2.defaultscope and declaration of variables:

In addition to the functions in the Local Variables , all other variables are global, meaning that their contents can be read or changed anywhere in the script. In addition, variables are not required to be declared; they are created whenever they are used ( each variable is initially empty / blank ).

1.3.storage of variables, stored in the variable poolmap ( varname,varval)

variables are defined with the Get def ("v1","val1"), Echo ($ ("$var 1"));

1.3.1.Compound Variables1.4.Variable TypeSimplify:string number, bool

AutoHotkey does not explicitly define variable types; All variables are stored as strings. However, when a variable that contains only numbers ( and can have decimal points ) is mathematically calculated or compared, it is automatically converted to a numeric value ( Integer or floating-point number, etc. ). Conversely, when the result of a mathematical operation needs to be stored in a variable, it is converted back to the string.
