TAS 6 Evolution has its own program to edit menus by user so each user can have their own menu. Standard DBA is more limited but you can edit the menu available to all users. It is a file named BKMENUW.ARY in the DBAMFG folder. Make a backup copy before you try making changes to it, it can be temperamental
Open it with NotePad and scroll down past all the comments at the beginning (lines beginning with a semicolon are comments) until you get to the first actual menu section, which is the WO menu. Look at the existing menu entries to see the way the items are set up and you should be able to figure it out. In the part of the menu line where the actual program name is specified (such as BKWOA for WO-A) make sure you have no spaces. That's one of the things it gets temperamental about.
