Filter Length Limitation

When a filter string is copied to or from the host from the standard filter dialog, the filter expression must be roughly 1900 characters or less. If not, a length error occurs and the complete filter expression is not copied. Filters that exceed this length (long filters) must be placed in the external filter library, and then referred to by name by using the Insert Class icon.

To create a long filter in the external filter library, select from the z/OS menu. This displays the External Filters/Classes Manager. External Filters/Classes Manager lets you define a filter of unlimited length and save it to the library.

Note: For more information, see the section External Filters/Classes.
