..MmoPackMethod is used to configure the compression mode of the MMO file (containing the binary and text memos) associated with a data file. You can:
  • find out the compression mode for a memo file (data file defined in the data model editor or defined by programming).
  • modify the compression mode of memos (data file defined by programming only).

Syntax

Finding out the compression mode of the memos Hide the details

<Current compression mode> = <File name>..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.
<File name>: Character string (with or without quotes)
Name of data file used. This name was defined in the data model editor or by the File description type.

Defining the compression mode of the memos Hide the details

<File name>..MmoPackMethod = <New compression mode>
<File name>: Character string (with or without quotes)
Name of 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.
