CLEARWIN_INFO@ parameters
An extra clearwin_info@ parameter has been added to help programs with several
edit boxes.
'ACTIVE_EDIT_BOX' returns the address of the EDIT_INFO array of the
currently active edit box. Notice that this edit box might not have focus if,
for example, the user had just moved to a menu item.
'EDIT_KEY' returns the ASCII value of the last key pressed. This information can
be obtained in response to a return of 'DATA_ALTERATION' from
clearwin_string@('CALLBACK_REASON'). In order to activate this feature you must
use the %eb[extended]. The call-back is called after the change has been made
so you will need to use one of the above editing functions if you want to undo
the key press.
