- # 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.
