New abilities?

Well, I tried to add some new abilities to AbilityData.slk using MS Excel 2002 (XP), but whatever I did, the new abilities did not appear in the editor. YES, I packed everything in war3patch.mpq. YES, I saved the file correctly and it was not corrupt.

Does anyone know what needs to be done in order to add a new ability to AbilityData.slk so that it appears in the editor? Speaking basically, if we have Give +1, +2, etc. to strength, how do we add +50 to strength in one ability?

(YES, I know that we can just add 50 abilities +1 strength, but I'm instead asking more generally - just how do I add a new ability type to SLK?)

Thanks in advance.

Hmm... thanks for a lot of helpful suggestions... OK, anyway, is there anybody on the 'net to help me?... Does anybody hear my question?...

First create the ability. The easiest way is to copy an existing one and changing its values. The edit the alias. Think/create a 4 letter code.

Then open units\******abilityfunc.txt and units\******abilitystrings.txt and take a look on that. Add you ability on those 2 files following any existing one.

BTW, ***** can be human, undead, .....

Those txt files will allow the ability to show up on the editor.
