_opcode_

| **Value** | **Description** |

| 0 | query drop buffer, set status parameter to the number of files in the drop target (ctlid) |
| 1 | retrieve fspec corresponding to fidx from the specified drop target (ctlid) |
| 2 | clear the contents of the drop target buffer |
| 3 | set non-destructive (previous "asynchronous") mode |


_ctlid_

_control ID of the target control_

**Response**

_status, fspec_ CR

_status_ values:  <=0 indicates failure, or no files available in opcode 0; >0 indicates success (number of files for _opcode_ 0 or the number of bytes in _fspec_ for _opcode_ 1)

_fspec_ is the file specification in opcode 1
