Size is a stack property.  I ran the same script, and got different results.
The first line of the file "Test Text" was interpreted as the name of a
stack.  The size of that stack was placed in the message box.  In other
words, HyperTalk dereferenced "it" before applying it as a parameter.

Of course, it is possible to say
  put it into message
and see the first line of your file.

Now, has anybody figured out how to determine the length of a record?
