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