# It then compares the line to TestDB.  If the line is found, the script
# exits.  if the line is not found, the script issues a warning and requests
# a go-ahead confirmation.

# The script will exit 0 if the test line is in the DB or the go-ahead

This dialect or its particular version may not have been validated

not even compile.
