**Throw( **[//error id//]// //**), VIRTUAL, PROC**

{{blk2blue.jpg|blk2blue.jpg}}

| **Throw** | Passes the specified error to the error handler object for processing. |
| //error id// | A numeric constant, variable, EQUATE, or expression that indicates the error to process. If omitted, Throw processes the current error--that is , the error identified by the previous call to SetError or Throw. |

The **Throw **method passes the current (last encountered) error to the nominated error handler for processing, including FILEERROR() and FILEERRORCODE() values, then returns the severity level of the error.

**Implementation:**

The SetError method saves the specified error and underlying error state for use by the Throw method. See //Error Class// for more information on error ids and severity levels.

The Init method receives and sets the error handler object.

**Return Data Type:**     BYTE

**Example:**

**Access:Client.Next FUNCTION(BYTE HandleError)!Next function**

** CODE                                        !with alternative error handling**

** LOOP**

**  NEXT( SELF.File )                          !get the next record**

**  CASE ERRORCOD()                            !check for error conditions**

**  OF BadRecErr OROF NoError**

**   RETURN Level:Benign**

**  OF IsHeldErr                               !if record is HELD by another**

**   SELF.SetError(Msg:RecordHeld)             !make RecordHeld the current error**

**   IF HandleError                            !if interactive error handling**

**    RETURN SELF.Throw()                      !pass current error to error handler**

**   ELSE                                      !otherwise (silent error handling)**

**    RETURN Level:Notify                      !return error code to caller**

**   END**

**  END**
