Checks the structural integrity of memos in a HFSQL file.

Example

Info("Memo corrupted")
END

Syntax

<Result>: Character string

Empty string ("") if there is no problem.
In case of problem, string in the following format:

<Item 1> + TAB + <Record number 1> + CR + ...
<Item N> + TAB + <Record number N>

where:
<Item X> is the memo item,
<Record number> is the number of the record containing the Memo item.
If the list of free blocks is corrupted, <Result> will contain:

<TAB> + "-1"

<Result> will have the following format:

<TAB> + "-1"+ CR + <Item 1> + TAB + <Record number 1> + CR + ...
<Item N> + TAB + <Record number N>

The list of free blocks is checked in HFSQL Client/Server only.
HCheckMemo is faster than HIndex associated with the hCheckMemo constant.
If a problem is detected, you have the ability to use HIndex associated with the hCheckMemo constant.
