SetVarType(var, type[, arraysize])

This function can be used to declare a variable. You only have to declare variables that are different from the default type (#LONG) and which do not have an identifier in their name like the "$" for strings or the "!" for floats. Arrays always have to be declared by specifying the optional argument arraysize.

var

variable name to declare

type

desired type (can be #LONG, #FLOAT, #STRING)

arraysize

optional: if you specify this argument, an array of the specified size will be allocated for you instead of a single variable
