Open Database Use this command to open other databases, up to a maximum of 20. You can also use this command to open an ASCII file up to 64K in length. After opening a database, you are shown a list of the databases currently open. QuickHelp searches for topics beginning with the database opened last. You can force QuickHelp to search a particular database first by closing the database and then reopening it. This technique is useful for avoiding duplicate topics in different databases and for speeding up the search time for a topic in a frequently used database.
