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:
hPackNoNo compression is performed on the memo file.
hPackZLWThe 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

<Data file>.MmoPackMethod = <New compression mode>
<Data file>: Character string
Name of the data file used. This name was defined by the File Description type.
<New compression mode>: Integer constant
The two compression modes are:
hPackNoNo compression is performed on the memo file.
hPackZLWThe memo file is compressed according to the Ziw-Lempel algorithm, Welch implementation.
