PrefixArea

HomePage | RecentChanges | EditorIndex | TextEditorFamilies | Preferences

"Full-Screen" or "Visual" text editors in the IbmEditorFamily have what is termed a "prefix area", which is a separate column from the file's text, in which "line mode" editing commands can be entered to insert, copy, move, delete or otherwise modify the file's content.

In Xedit the area can be set to appear to the left or right of the file's text (or turned off), and can be set to show line numbers, equal signs (=====) or spaces.

In ISPF/PDF it is displayed on the left and shows the line number; ICCF it is displayed on the right side of the screen and contains equal signs.

where nn is the number of lines affected. For Show Lines, in Xedit when nn is positive the first lines of an excluded group are shown; when negative, the last lines. The default for nn is 1 except for the ISPF/PDF shift commands, where it is 2.

In Xedit, nn may precede the line command.

Xedit allows the user to mark a line with a symbolic name (xxxx) which may be used to refer to that line in primary (command line) commands.
