========================
1. Important information
========================

To encapsulate the demands on a modern Graphical User Interface, the IAR
Embedded Workbench runs only under the following operating systems;
Windows 95/98 and NT 4.x.


Additional documentation:
-------------------------

Apart from the manuals, supplementary information was installed in the
different component subdirectories during installation. It is HIGHLY
RECOMMENDED that you read these files as they contain information that
did not make it into the manuals.

The file "deislxxx.isu":
------------------------

After installing the IAR Embedded Workbench, you will notice a file named
"deislxxx.isu" located in your target installation directory (xxx is
a number). This file contains uninstallation information to enable you to
automatically uninstall the Workbench  by opening the control panel
"Add/Remove programs". Although deleting this file does not affect the
operation of the Workbench, it does mean that you can not automatically
uninstall it.

Misc. error dialogs during building:
------------------------------------

If you repeatedly get error dialogs giving generic error messages like
"Error running tool" when building a particular file, the likely cause
is a problem in the tool, not in the workbench itself. Most probably
the tool runs into problems dealing with a particular construct in the
input file. There are two different ways of finding the cause of the
problem:
1) If you have a command-line version of the tool available, run it
   with the same options and note if it produces any error messages.
   (The options used when running a tool in the EW can be seen in the
   message window if message filtering is set to "all".)
2) Try to comment out part of the input and see if that makes any
   difference.
The cause of the problem may be erroneus input (which arguably should
be reported properly from the tool) or it may be a program error.

External editor configuration:
------------------------------

As different DDE capable editors use different commands, it is necessary
to consult the user documentation supplied with your editor to find the
correct command syntax.

Here are some example configurations for particular editors:

EasyCase

Editor: C:\EASY\Easy-cpp.exe
Service: easy-cpp
Command: system [line($CUR_LINE$)] [load("$FILE_PATH$")]

Codewright

Editor: c:\cw32\cw32.exe
Service: Codewright
Command: System BufEditFile $FILE_PATH$
         $FILE_PATH$ MovToLine $CUR_LINE$

Note that there seems to be a problem with Codewright that can
cause the selected buffer to be activated in the background,
but when bringing Codewright to the foreground, it may revert
to the previously selected buffer. To work around that problem,
use this command configuration instead:
  System OutputWindow=1
  System BufEditFile $FILE_PATH$
  $FILE_PATH$ MovToLine $CUR_LINE$
The first command is equivalent to clicking on a tab in the
Codewright Output Window, bringing it to the foreground before the
other commands are issued.

Avoiding absolute paths in project options:
-------------------------------------------

In EW 2.31A and later, it is possible to use argument variables in
project options. This makes it possible to make projects more portable
between different environments by avoiding unnecessary absolute paths.
The most obvious use for this is to make include options and xcl-file
options compiler and/or project relative.

Example:
  Setting an include option to "$TOOLKIT_DIR$\inc\" would make the
  build tool look for include files in the "inc" subdirectory of the
  active product (i.e. standard system includes).
  Setting an include option to "$PROJ_DIR$\inc\" would make the
  build tool look for include files in the "inc" subdirectory of the
  current project directory.

The following argument variables can be used:
Variable	Description
$CUR_DIR$	Current directory
$CUR_LINE$	Current line
$EW_DIR$	Directory of the IAR Embedded Workbench, for example c:\iar\ew23
$EXE_DIR$	Directory for executable output
$FILE_DIR$	Directory of active file, no file name
$FILE_FNAME$	File name of active file without path
$FILE_PATH$	Full path of active file (in Editor, Project, or Message window)
$LIST_DIR$	Directory for list output
$OBJ_DIR$	Directory for object output
$PROJ_DIR$	Project directory
$PROJ_FNAME$	Project file name without path
$PROJ_PATH$	Full path of project file
$TARGET_DIR$	Directory of primary output file
$TARGET_FNAME$	Filename without path of primary output file
$TARGET_PATH$	Full path of primary output file
$TOOLKIT_DIR$	Directory of the active product, for example c:\iar\ew23\a90

2. Manual corrections and updates
=================================

Additional documentation:
-------------------------
EWA90 V1.50B 4/February/00

* The XLINK options control panels have been updated to reflect
  new XLINK features.

  The section "Warnings/Errors" on the "Diagnostics" page contains
  three new fields: "Suppress these diagnostics", "Treat these as
  warnings" and "Treat these as errors". In these fields you can
  give a comma or space separated list of diagnostics that you
  want to reclassify. (This is the "-w" command line option.)
  Example:
    "Suppress these diagnostics" w26, e106

  The "Output" page contains a new drop-down list "Module-local
  symbols" that allow you to specify inclusion of module-local
  symbols. (This is the "-n" command line option.)


  For further information about XLINK option, refer to the file
  "xman.txt"

EWA90 1.02A (Beta) 23/Sep/96

* p49 'Options': There is an additional button "Factory
  Settings" appearing over the property pages. Pressing it reverts all
  options for the selected item and category to the original, default
  setting (release or debug).

* The manual mentions some *.doc files, 
  but most of these have been renamed *.txt

* Two comments regarding the assembler tutorial (using 'first.s90') in the 
  Embedded Workbench:
  - The example does not work unless you select an appropriate linker
    file (\iar\a90\tutor\first.xcl). The default gives segment overlap.
  - The example sets up -v1 -ms. Still, in the example, JMP is used 
    instead of RJMP in the eternal loop.

3. Known problems in current version

  * none.
