| 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. |
