-# Commands covered: expr

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