Close files and release public and private variables
CLEAR ALL releases all public and private variables, closes all open databases and related files in all active work areas, and SELECTs work area 1. Related files are index, alternate, and memo files. CLEAR ALL, however, does not release local or static variables.
CLEAR ALL is a compatibility command and therefore not recommended. Its usage in Clipper is superseded by the command or function that performs the specific action you need. You can close files associated with work areas with one of the various forms of the CLOSE command. You can release private and public variables using the RELEASE command although explicitly releasing variables is discouraged in most instances. For more information on the scope and lifetime of variables, refer to the “Basic Concepts” chapter.
