Fabio, this is very strange. In that thread, Andrew uses the code:

release x
x=sys(1104)
? x
?type(x)

First of all, notice that when you get the result of '? x', the '0' (or whatever number) has no leading spaces - therefore it is a string.

Also the whole thing doesn't seem to make sense. The syntax for Type() should have been Type('x'), and that returns 'C', not 'N'.

Try this:

Release y
y = 5
? y
? type(y)

First, the '? y' produces 5 with leading spaces. And then you get an error on Type(y). Why no error on Type(x)?

x is an address pointer pointing to a string?
