+ 1. Download https://sourceforge.net/p/oberon/oberonv4/ci/master/tree/Windows/Kernel.Mod to $User 
+ 2. Open it in OberonV4 for Windows
+ 3. Use Folds.Compile from Menu->Compile
+ 4. Rename/Save Oberon.Hex in the main installation directory of Oberon V4 for Windows
+ 5. Open $Text/Develop.Tool
+ 6. Scroll down to **2.) Make boot file** and find the line "BootLinker.Link Oberon.Hex := Reals Console Kernel ShowError Registry Directories Files Modules ~" . Middle mouse buttom click on BootLinker.Link
+ 7. Leave Oberon V4 for Windows
+ 8. Find the new Oberon.Hex (most probably in subdirectory User of the main installation directory of Oberon V4 for Windows) and move/copy it to the main installation directory of Oberon V4 for Windows

Tools

You can find the following tools in the V4 sources repository in the utils folder.

OberonFilter

This java program allows one to view the content of an Oberon Text file. It requires Apache commons libraries IO and Lang

Compile

javac ch/claudio/oberon/OberonFilter.java

and run

java -cp .:commons-io-2.4-jar:commons-lang3-3.1.jar ch.claudio.oberon.OberonFilter -?

to show the usage.

It expects to read an Oberon Text file from STDIN and outputs to STDOUT.

Without any options it will write pseudo-XML which contains all information gathered from the Text file. By adding the -nopos Option the pos-Attribute will be suppressed. This form is better suited when you want compare the output with some other file.

With the -plain Option a plain Ascii file is created, stripped of all formatting and with the Oberon end of line character CR converted to NL. Ctrl-Chars except TAB are stripped too.
