HSetMemo (Function)

Used to modify the management mode of memo items. You have the ability to manage all the memos of a data file or a specific memo item of a data file. The management of memos is enabled by default.

The management of memos can be implemented for the data file only: the memos cannot be managed for the items.

(default value) The memos are read during the access to the item.
hMemoYes The text memos are read whenever the record is read.
The binary memos are read during the access to the item.
hMemoNo No management of memos (no read or write operation will be performed on the data file or in the specified item).

<Data file>: Optional character string (with or without quotes)

<Management mode>: Integer constant

Management mode of the memo items:
hMemoAuto

The binary memos are read during the access to the item.
hMemoNo No management of memos (no read or write operation will be performed on the data file or in the specified item).

If only this parameter is specified, the management mode is applied to all the data files and to all the items.
