# 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.
