# Commands covered: expr
#
# This file contains the original set of tests for the compilation (and
# indirectly execution) of Tcl's expr command. 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.
