# Commands covered:  while

#

# This file contains the original set of tests for Tcl's while command.

# Since the while command is now compiled, a new set of tests covering

# the new implementation is in the file "while.test". Sourcing this file

# into Tcl runs the tests and generates output for errors.

# No output means no errors were found.
