Multiple Line Editor
The keyword STDEDIT invokes the system editor for a Text object. If a file
name is specified, the system editorÕs Exit Menu will be accessible.
FEDIT
or
FVIEW
provide a quick way to invoke the system editor on a file.
Customized Editors and Menus
The keywords EDOPEN , EDCTL , EDWRITE , EDKEY , and EDCLOSE
allow you to create menus and editors with customized behavior. Also,
SET-
TARGET , GETTARGET allow program control over searching for targets
in an editor or menu. The Display Editor in OPEN is an example of a custom-
ized menu. This routine shows the makeup of OPENÕs display lines, and al-
lows the user to edit them. An abbreviated listing of this routine is shown in
Figure 23-27. Note the inclusion of the file
“/Sys/Lib/CEDefs”
, which contains
useful tools for these operations.
