# Commands covered:  set, unset, array

#

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

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

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

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

# No output means no errors were found.
