 # 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 avoids the need to maintain 'CNTLIN' datasets seperately to the main catalog.
+Data Controller allows formats to be viewed and edited directly from the web interface - avoiding the need to create and maintain parallel 'CNTLIN' datasets.
 
 Formats are displayed with a special icon (`bolt`), in the same library as other tables (in both the VIEW and EDIT screens):

 Viewing or editing a format catalog will always mean that the entire catalog is exported, before being filtered (if filters applied) and displayed.  For this reason, it is recommended to split a large format catalog over several catalogs, if performance is a consideration.
 
 The usual export mechanisms can also be applied - you can downlad the DDL, or export the catalog in CSV / Excel / Datalines formats.
 
-When adding a format to MPE_TABLES, the `DSN` should contain the format catalog name plus a `-FC` extension.  The LOADTYPE should be `FORMAT_CAT` and the BUSKEY should be `FMTNAME START`.  HOOK scripts can also be applied (run some DQ after an edit, or re-run a batch job after an approval).

-Just like regular table edits, all changes may also be logged in the `MPE_AUDIT` table.
