Model II
TRSDOS
Quit Option: Ends the editing session. All remaining lines will be copied into
the new file as-is. Before closing the file,
TRSDOS
will ask you if you want to
add new lines to the end. (If you simply want to add to a file but make no other
changes, type
Q
at the beginning of the edit session.)
At end of file
Whenever
TRSDOS
reaches the end of the file, it will ask if you want to add
new lines at the end. Type Y to add, N to end the editing
seSSIOn.
Adding lines at the end of a file is just like using the insert line option
described above. Type at the beginning of a line to stop adding and
close the file.
To recover a BUILD file's previous contents
There are a couple of cases in which you may need to do this. Let's assume you
are editing a file named
STARTER.
1. After ending the edit session, you realize that you have made an error,
and you want to recover the previous version of the file.
2. You accidentally press
that have been flagged like this:
and end the edit session; only those lines
*** LINE STORED IN FILE ***
will be saved in the new file named
STARTER.
The previous file contents are now stored in
STARTER/OLD.
If you want to re-
edit this file, you must Copy it or Rename it to a file name without an
extension. For example, you might use this command:
COpy STARTER/OLD TO STARTER {ABS}
(See
COpy
for an explanation of the
ABS
parameter.) Now you can edit the
previous file's contents. Type:
BUILD STARTER
to start editing.
