Description
These rules apply when deleting files:
You cannot delete a dictionary file that points to one or more data files.
You cannot use DELETE-FILE to delete Q-pointers in the Master Dictionary that are used as file synonym definitions.
While the DELETE-FILE processor is working, the BREAK key is disabled.
When you delete a file, the DELETE-FILE processor removes the File Definition item from the Master Dictionary and releases all frames allocated for the file.
|
CAUTION |
Use this command with care. The system does not ask you to confirm the operation before it deletes the file. |

SALES is a dictionary shared by multiple data files. You can delete the dictionary and all its associated data files with a single command:
