JBTree
Version 4.2.4
(c)JBSoft 1992-5
This is a program which displays the directories and files on any disk
(internal or external). It shows the current directory and other
directories at the same level, plus any directories immediately
subordinate to the directory on which the cursor is on. It also
displays the files in the current directory - the date will take the
same format as that set in the Time application. The program is free
for your use but I retain all copyright on the code (where applicable
- some of the Pack information was provided by Wolfgang Schirmer and
Matthew Millar - thanks).
N.B. If you can't be bothered to plough through this document please
note that Copy, Move etc. only work after you have Marked the
file using the Space Bar or the Enter key. Also, for
installation, please read that section or you'll be sorry <g>!
Background
----------
This utility was first started in the days of the Series 3 but I only
got it to a reasonable state on the appearance of the Series 3a. It
has been translated, and therefore will only run in its present state,
on an S3a although I suspect it could be adapted to compile and run on
an S3 with some compromises. There are some limitations which I
suspect you will discover as you use it.
Manual and Usage
----------------
This is work in progress (I suppose, as I keep changing it) and so it
comes without a proper manual (it's also got fairly complex and I
don't really have the time to write a proper one). This document is
getting close to turning into a manual as I expand on it. Help is
available on the HELP key at most times and, as with most OPL
programs, you can escape using Psion-Esc or Psion-X at almost any
time.
The history information (which used to appear at the end of this text
file has been moved to a new file called JBTHISTR.TXT as it was
getting rather large.
Installation
------------
The files listed below should be part of the JBTree ZIP file:-
JBTREE.OPA - The main part of the program
JBTL.DBF - Install if Launch is to be installed
JBTREE.DBF - Data file required for View/Run options
JBT.DBF - My example file of JBTREE.DBF (included as part
of the explanation - should not be installed
JBTREE.TXT - This file/manual
Copy JBTREE.OPA to any directory (normally \APP\ but this is not
mandatory) and install it in the usual way using Psion-I. If you
require to view files using their native application then the file
JBTREE.DBF should also be placed in the \APP\ directory. When JBTree
is first run the file is moved to a sub-directory off the directory
JBTree is installed in called \JBTREE\ (e.g. \APP\JBTREE\).
This sub-directory drive for the configuration files can be chosen
and, if the JBTREE directory does not exist, then a dialog to choose
the drive will be given. The directory should be created automatically
- if not, it is permissible to generate it manually. Please note that
if the parent directory (normally \APP\) does not exist then this
automatic installation may fail.
If you are updating your version then you will have to manually move
the configuration files to the appropriate directory. The program
looks for these files in a directory off the directory that JBTREE.OPA
is in (i.e. if JBTree is in \JBT\ then the configuration files MUST be
in the directory path \JBT\JBTREE. This path can, however, be on a
different drive to that of the OPA file.
There has been one instance of the directory not being created of
which I am aware although this problem was not repeatable.
If you require the Launch menu then JBTL.DBF should also be placed in
the \APP\ directory. This will be moved to the appropriate directory
by the main program when it is first started.
N.B. Care should be taken when upgrading the program - no datafiles
will be overwritten if they already exist in the \JBTREE\
directory when the program is started. If you wish to upgrade (or
replace) the datafiles then the original datafiles in the
\JBTREE\ directory must be deleted first or the files concerned
manually transferred to this directory.
JBTL.OPO which was required for version 4 and 4.1 is not now
needed and will be automatically deleted when JBTree is first
run.
Starting the program
--------------------
To start the program place the cursor on the JBTree word and press
Enter to start the program.
After starting the program you are prompted for a Drive - if the 3-
Link is active then, before the drive menu is accessed, a choice of
Local or Remote is given. Remote means drives on the remote computer.
If the drive you wish to access is not shown on the menu then press
Esc and you can then select almost any drive (including the ROM) with
the dialog displayed at this point.
N.B. If the letter keys (e.g.'F') do not appear to work or do not work
as expected, check that you do not have CAPS LOCK on. The S3a is
case sensitive on the keys checking. Unfortunately, unlike the
good old Organiser II, it does not appear possible to alter the
state of the CAPS LOCK from within the program using OPL so
please be sure that this is switched off whilst using the
program.

Moving Around
-------------
Use the cursor keys in the normal way. To go to a sub-directory use the
right arrow key, to go to the parent directory above the present one use
the left arrow key. To flip between the Directory list and the Files list
use Tab or the Diamond key. If in the Files list then Escape will also take
you to the Directory list. To change the drive use Psion-D whilst in the
directory list. An alternative, if just the local drives are required, is
to use Ctrl-A -B or -M. This bypasses the dialogs and so speeds up the
selection a little.
It is possible to jump to a directory or file within the current list by
using 'c' where
