SELECT ERROR
General Form:
SELECT ERROR >error_code
Where:
error_code = a computational error 60-69.
The ERROR select parameter is used to suppress system error messages caused by computational errors.
Normally, when a computational error occurs the system displays the appropriate error message. If a computational error is detected after a SELECT ERROR statement, the error message is suppressed and the receiver variable is set to the default value.
| Error Code | Error Condition | Value Returned |
|---|---|---|
| 60 | Underflow | 0 |
| 61 | Overflow | + 9.999999999999E99 |
| 62 | Division by zero | + 9.999999999999E99 |
| 63 | Zero / or ^ zero | 0 |
| 64 | Zero raised to negative power | + 9.999999999999E99 |
| 65 | Negative number raised to non-integer power | ABS(A) ^ B |
| 66 | Square root of negative value | SQR(ABS(A)) |
| 67 | Log of zero | - 9.999999999999E99 |
| 68 | Log of negative value | LOG(ABS(A)) |
| 69 | Argument too large | 0 |
The value of SELECT ERROR is reset to the default upon execution of a CLEAR, LOAD RUN command, or by entering SELECT ERROR >60.
Syntax examples:
SELECT ERROR > 65
SELECT ERROR > error_code, PRINT /005
