several problems here...

  1. you cannot do a full 80 columns because most all terminals
     will automatically wrap to the next line when you write to
     the 80th column...

  2. 24 lines is generally ok but you don't know if the user
     has their terminal status bar on or off...

  3. 1 and 2 together - when you try to write a character to
     the 80th column on the 24th (or 25th) line... not only
     do you get terminal wrap but also terminal line feed...

you're better off to go with 79x23 or even 78x23 and leave a blank/black one column wide band on the left to match the one on the right that you can't write to...

remember, also, that these two empty/unused columns could be "not black" if you set a background color and then clear the screen...

  4. don't count on terminals wrapping at column 80...
     depending on a user's settings in their terminal, it
     may sit there and draw other characters in that one
     spot...

there's another one but i can't think of it at the moment... it is another corner case like the ones above, though...
