1# Commands covered: expr
2#
3# This file contains the original set of tests for Tcl's expr command.
4# Since the expr command is now compiled, a new set of tests covering
5# the new implementation are in the files "parseExpr.test" and
6# "compExpr.test". Sourcing this file into Tcl runs the tests and generates
7# output for errors. No output means no errors were found.
