# Commands covered:  for, continue, break

# This file contains the original set of tests for Tcl's for command.
# Since the for command is now compiled, a new set of tests covering
# the new implementation is in the file "for.test". Sourcing this file
# into Tcl runs the tests and generates output for errors.
# No output means no errors were found.
