Example
float main()
{
try
{
int dividend = 10;
int divisor = 0;
if (divisor == 0) //division by 0 error
{
errClass err = makeError("", PRIO_FATAL, ERR_CONTROL, 0, "Division by zero error");
setErrorUserData(err, makeDynInt(dividend, divisor));
throw(err);
}
return dividend / divisor;
}
catch
{
dyn_errClass exceptions = getLastException();
dyn_int operationValues;
getErrorUserData(exceptions, operationValues);
DebugN(getErrorText(exceptions), "Dividend = " + operationValues[1], "Divisor = " + operationValues[2]);
return maxFLOAT();
}
