CDE and gencat

Each platform has its own implementation of gencat. Follow these rules for message catalogs to ensure that each message catalog's format does not cause different gencat utilities to break:

1. Use a $quote directive if you have trailing spaces (see the gencat man page).

2. Do not put more than one space between the message id and the message string.

3. Insert a space between $ and the comments.

4. Message IDs need to be sorted in ascending order.
