About Larsen Commander, version 1.5
Larsen Commander is a powerful GUI File Manager and Command Processor that
has a look and feel like the classic Norton Commander. The most notable
difference is that the Larsen Commander is pure GUI. Still it has a built
in command line and a scrollable console monitor.
Larsen Commander is shareware. In other words you can use it freely only
for a limited period of time which should not exceed one month. If you
use Larsen Commander regularly for a longer period then you must register
your copy so that further development of it can take place.
You can freely distribute Larsen Commander as long as you don't change it
or sell it and as long as this readme file is contained in the distribution
together with the program.
Larsen Commander requires OS/2 Warp 3 or higher. It is compiled for
usage on 80486 processors, or higher. It was developed and built using
IBM Visual Age C++ 4.01 for OS/2. Great parts of the Larsen Commander
have been developed and tested on relative slow computers and therefore
performs very well even on relatively weak machines.
On power machines the Larsen Commander is flying...
To install the product you can follow these steps:
1. Unzip the distribution archive file in the directory of where
you want to install the program.
2. Run the script LCMDINST.CMD that is part of the distribution.
This will create a Larsen Commander folder on your desktop.
This is all.
Upgrade from version 1.1.x
To upgrade from Larsen Commander version 1.1 to version 1.5 you can
follow these steps:
1. Backup all the 1.1 files, including the INI-file, in case you will
experience problems with version 1.5 and you will need to revert to
version 1.1 while waiting for a fix.
2. Unzip the 1.5 distribution archive in the same directory as of where
Larsen Commander 1.1 is installed.
3. Run Larsen Commander. You don't have to execute the LCMDINST.CMD script,
unless you want to recreate the Larsen Commander folder on your desktop.
NOTE: Due to a number of changes in the way Larsen Commander 1.5 reads
and uses the content of LCMD.INI (with respect to version 1.1) you
will likely experience that at least some of your original
configuration is lost when you upgrade to version 1.5. You should
consider deleting the LCMD.INI file from version 1.1 and let
Larsen Commander 1.5 create a new one for you. This will clean out
some unused entries, and it will make Larsen Commander 1.5 start
up slightly faster and possibly use somewhat less memory.

Known bugs and problems
1. Some programs uses the VIO subset of OS/2 in such a way that they can not
be run as a child process in the console monitor of Larsen Commander.
You can execute such programs by pressing ALT+ENTER rather than just
ENTER. This will ensure that the program is run in a new session,
completely independent from Larsen Commander.
This is a common and well known problem not only to Larsen Commander
but also to other GUI shells, such as Take Command/2 and the SHELL
facility of the OS/2 EPM Editor.
Anyway, you can always press CTRL+C to break the current child program
should it operate in an unaccessible way.
To make Larsen Commander automatically run the program in a new session,
regardless if you execute it with ALT+ENTER or just ENTER, just add
the program name to the list of TTY-apps in the options
dialog (Options->Jump To->Commands->TTY-Apps).
2. Some of the menu commands in Larsen Commander depends on external
programs on your system. For instance, when you choose to edit a text
file from within Larsen Commander, by default the OS/2 standard text
editor program E.EXE will be launched. However, you can easily choose
another program module if you like (probably you will). Just open the
options menu and select "Programs...". Then, just type in the desired
program module name and parameter list of each program category.
A few of the default programs are shareware programs that you might
not have installed on you system. For instance, when you choose the
menu command for comparing the content of two text files, Larsen Commander
will (by default) try to launch the PM-Diff shareware program.
I am working on internal versions of some of those menu commands.
