I am using OOo 1.1.1rc
I have verified that user defined structures work, but when I initially tried my
own user defined structure, OOo would completely crash if I had an incorrectly
defined struct. The following example contains the error. Be warned, do NOT save
the library that contains this code because the only way that you will be able
to delete it is to manually edit the library on disk. The very act of opening a
library that contains this code will lock OOo 1.1.1rc on my linux computer.

Of course, remove the extra Dim statements and this works just fine! Good Job on
that AB!

Type PersonType
  Dim FirstName As String
  Dim LastName As String
End Type

Sub ExampleCreateNewType
  Dim Person As PersonType
  Person.FirstName = "Andrew"
  Person.LastName  = "Pitonyak"
  PrintPerson(Person)
End Sub

Sub PrintPerson(x)
  Print "Person = " & x.FirstName & " " & x.LastName
End Sub
