There's nothing that ever sets env vars to the screen size.

However, if you use bash, it will set _shell_ variables, COLUMNS and
LINES, automatically. This isn't something that screen does, but bash.
Bash does _not_ export these by default, however; you'll need to do

 $ export COLUMNS LINES

to get them into the environment. Of course, if you're not running bash,
you may not have them at all; in which case you may need to parse them
out of the screen-supplied TERMCAP (which, unlike the bash vars, can't
be kept up-to-date when the window size changes).
