# 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.
