# 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.
