+description: Viewing and Modifying SAS Formats in Data Controller
+---
+
+!!! warning
+    Work in Progress!
+
+# Formats
+
+SAS Formats are stored in Catalogs, and are used for in-memory lookup operations.  Some formats are available by default, others (custom formats) are maintained seperately.
+
+Using Data Controller to manage formats means that it will no longer be necessary to maintain 'CNTLIN' datasets seperately to the main catalog.
+
+Formats will be presented with a new icon (`bolt`), in the same library as other tables (in both the VIEW and EDIT screens):
+
+![formats](https://i.imgur.com/rnQOLlv.png)
+
+Viewing a format catalog will always mean that the entire catalog is exported and displayed.
+
+Filters will be applied after the export.  DDL / excel exports will apply to the export.
+
+The MPE_TABLES for formats will need to be configured with a new LOADTYPE (FMTCATALOG) and specific CLOSE_VARS and BUSKEY values.
+
+Edits to formats will follow the regular approval process, with changes logged in MPE_AUDIT.
