dim declares a new variable.
The variable has a name and either a type or an initial value.
If an initial value is provided, then the type is inferred from that value.
If a type is provided, then a default initial value is chosen for that type.Use const to declare a constant that cannot be changed.Use dim list, dim map, and dim set to efficiently build the contents of a collection at the same time as declaring it.
dim <VARIABLE> as <TYPE>
dim <VARIABLE> = <VALUE>
<VARIABLE> is the name of the new variable to declare.
