I missed the "sort" feature from the RADIAS editor, so...
I wrote a java program. It's can open a rdl file, read the programs from the file, sorting by name, or by category or by both, then create a new rdl file with .sorted.rdl extension... The opened, original file not modified just had read!
Of course the other data like global parameters, etc are also writing in the new file!
I don't know is there anybody who is need some similar, but you can download from my site (http://lipi.atw.hu) and then you can run it on your computer. It's can't run by webstarter!
Thankfully for the java it's platform independent

Only one stuff you need is the latest JRE...
A sort video about usage
If you think it's a good or usable utility please reply!

Thanks!
