I suspect you're used to working in a language that has typed variables.
Lingo's variables are untyped. That is, they will accept anything you
give them--a string, an integer, a property, a real, a linear list, a
property list, a pointer, or any type of value. You can change type in
midstream. For example:
x = 10 -- x is an integer
x = "10" -- x is now a string
x = [10] -- x is now a linear list with one integer element
x = ["10"] -- x is now a linear list with one string element
x = "[10]" -- x is now a string
x = #ten -- x is now a symbol represented in your source code by #ten
Setting theDefault to #string makes theDefault a symbol which you can
access with #string. It doesn't make theDefault a string. It makes it a
symbol.

Set it explicitly to a list. For example:
x = [10, 20] -- x is a list
x = value("[10, 20]") -- x is a list
The following will not create a list
x= "[10, 20]" -- x is a string
x= value ("10") -- x is an integer with a value of 10
I think the main thing to remember is that Lingo variables aren't typed
at all, except by what you assign to them. Also, #string is a symbol,
and doesn't really have anything to do with a string variable.
Cordially,
