This configuration variable controls whether a warning message is printed when non-numeric data is used in a context where numeric data is required. There are four settings:
| 0
| (off, false, no) No warning is printed.
|
| 1
| (on, true, yes) A warning is printed. This is the default.
|
| 2
| A warning is printed. If you are in the debugger, an automatic breakpoint
occurs.
|
| 3
| A warning is printed and the runtime shuts down. |
