That sounds easily do-able.

Advice: don't do it that way. Make it a scrollable text field, put your 
36 lines into it, leave it positioned so the top of the field is visible 
- and then let the user scroll the field to read the rest of it when she 
is ready. The scrollbar will make it clear there is more there to be 
read - and nowadays everyone is familiar with scrollbars, and can choose 
the means they prefer (arrow key vs. page-down key vs click in scroll 
area vs scroll wheel vs ....) to scroll as they wish.

Pointer to a solution: check in the docs for "formattedHeight"
Note you can do something like
     get the formattedHeight of line 1 to 16 of field "OutputText".

But use the advice not the pointer :-) :-)
