Display dialog with multiple input lines?

Question 1:

I want to display a dialog window that can capture some 8 or 10 lines of text in my small app to send email thru “telnet”.

I mean I try to:

code

set myVariable to display dialog “Write here your email body” buttons “ok”

But only get a small box, that I can not see the whole text. (some 8 or 10 lines)

Is it possible to get a larger text box?

Question 2:

Once I paste or write my text in the dialog box, it adds “;Ok” to the end of the text returned.

How can I avoid it?

Thanks!
