Recovering Deleted Items: RECOVER-FD Command

Recovers an item after it has been deleted by the FD command in the Editor.

Command Class

TCL-I command.

Syntax

RECOVER-FD file-specifier

Syntax Elements

file-specifier specifies the name of the file that contains the deleted item.

Prompt

Item Id:

RECOVER-FD prompts you for the item-id of the item that was just deleted. If the item-id matches the last one used by the Editor, the item is restored. The message 'item-id' filed in file 'file-name'  is displayed and control returns to TCL.

If the item-id you type does not match the last one used by the Editor, you are again prompted for an item-id. RETURN or LINE FEED entered as a response to the Item Id:  prompt returns the process to TCL without recovering the item.

Limitations of Recovery

RECOVER-FD must be issued immediately after you execute an FD command or the item is lost permanently. Deleted frames are returned to overflow space.

RECOVER-FD never works if the ED{IT} command was called from a DataBasic program or from a Proc.

RECOVER-FD works only if the deleted frame has not been claimed from overflow by another process and, if a list was edited, it was the last item in the list.
