In french: CompressionMMO

Available only with these kinds of connection

The MmoPackMethod property is used to set the compression mode of the MMO file (containing text and binary memos) associated with the data file. You can:

find out the compression mode of a memo file (data file defined in the data model editor or through programming).
modify the compression mode of the memos (data file defined through programming only).

Example

// Description of a data file through programming
AFile is File Description
// Modify the compression mode of this data file
AFile.MmoPackMethod = hPackZLW

Syntax

Finding out the compression mode of the memos Hide the details

<Current compression mode> = <Data file>.MmoPackMethod

<Current compression mode>: Integer constant

The two compression modes are:
hPackNo No compression is performed on the memo file.
hPackZLW The memo file is compressed according to the Ziw-Lempel algorithm, Welch implementation.

<Data file>: Character string

Name of the data file used. This name was defined in the data model editor or with the File Description type.

Defining the compression mode of the memos Hide the details
