# CVLEN is just the *estimated* never to be exceeded amount of storage needed
# to set up the escape sequence. It could be determined dynamically by
# changing cv_move to count elements instead of moving them. Then the known
# counts would be used with amovs to hustle the elements into the "salloc'ed"
# space. Instead, with a static count, we can salloc once upon entering
# the cv program and free up at exit.
