After a significant rework, many new features were added, and the first usable version of the MADS integration is now available. Now "only" content outline and label file creation are unavailable. I know many people are waiting for the content outline, but I first had to get the syntax for all definitions of pseudo opcodes and directives straight and extend the parsing to block comments. Otherwise, parsing for a content outline is not possible. And comparing the 61 definitions in ATASM (described in an English manual) to the 168 (!) definitions in MADS (described in a Polish manual), you may understand what kept me busy in the past weeks. And without the incredible support from Tebe for the technical details, it would not have been possible! Also, my wife did a great job translating the MADS manual's relevant sections for me, so thanks for that!

Unfortunately, starting the emulator automatically on Mac OS X does not work. But I have a Mac OS X emulation up and running now for my tests and found out that the problem is passing parameters to the "open" command and the binary file name.

You can use the menu entry "Help/Software updates/Available Software" to update from version 1.1.0 to 1.2.0.

Features: See the tab "Features" on WUDSN IDE for screenshots
