Drawing in a Form's Window?

[Michael B. Allen]

Can I write to the window of a form or menu? I tested writing text
between elements of a form and provided it was written after the form
was posted it would work. However, I assumed that because the tutorial
suggests using non-O_ACTIVE fields as labels that you're confined to
using only fields withing a form's window. Or was that simply describing
a technique for altering a labels value dynamically?
