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