RE: how to set frame parameters?

[Drew Adams]

the length set to the size of the screen where I'm working.  I had a function that calculated the maximum length (max-lines) that I could use for the window.   

This is what I would do:

 

  (/ (x-display-pixel-height) (frame-char-height))

 

That gives you the max height in number of lines, which is what you want, if I understand correctly.
