WARNINGS* - 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 possible 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.
