Specify the compression format for values in a list.


[Miscellaneous]    ListFormat=n

n is an integer in the range 0—3. The default value is 0.



This parameter has been retained for compatibility, but should not be used when building new applications.

ListFormat determines which values should be compressed within a list. The possible options for ListFormat are:

  • 0 — no compression in a list

  • 1 — $DOUBLE (IEEE) values in a list are compressed

  • 2 — Unicode strings in a list are compressed

  • 3 — Both $DOUBLE and Unicode strings in a list are compressed


If using lists with external clients (Java, C#, etc), ensure that the external client supports the compressed list format.

Changing This Parameter

On the Compatibility page of the Management Portal (System Administration > Configuration > Additional Settings > Compatibility), in the ListFormat row, click Edit. Enter the desired value for this setting.

Instead of using the Management Portal, you can change ListFormat in the Config.MiscellanousOpens in a new tab class (as described in the class reference) or by editing the CPF with a text editor.
