ined by the position of the cursor. The box defined by the mar-
ker and the cursor is used by the CUT key.
In box mode, all of the text which is inside the box will be CUT
out, and replaced by spaces. For a PASTE, the box in the paste
buffer will overlay any text when in it pasted in. The cursor

TPUR will edit files /READ_ONLY, and will not use a journal
file.

to be edited, whether or not the file should actually be
edited. You can answer Yes, No, or Quit. The default is
not to edit the file. Quit will cause APLTPU to stop
searching for files.
Example:

the keystrokes you enter will be remembered unitl a CTRL/R is
entered. The next time that you use the newly defined key,
the keystrokes for the key will be performed again. Note that
