Q: How can I tell what NLS Catalog File (.CAT) goes with which (Sub)Application?
Problem
There are many NLS Message Catalog (CAT) files shipped with VA Smalltalk. How can I find the (sub)application associated with a particular CAT file?
Solution
The following 3 tables cross-reference (Sub)Applications, NLS pool dictionaries, and Catalog files.
(Sub)Applications to Pools and Catalogs
 
Pools to (Sub)Applications and Catalogs
 
Catalogs to (Sub)Applications and Pools
VA Smalltalk ships some NLS catalog files that are no longer used, but are kept for backward compatibility. Where the original use of the files is known, it is noted in the table.
