There was never a wordfile included in UltraEdit installer package for files with extension PAS. But take a look on Downloads - Extras - Wordfiles. There you can find user-submitted wordfiles for Pascal and Delphi for UltraEdit.
I happen to have wordfiles for Delphi that I use with Delphi 2010. These have been expanded beyond the standard Pascal wordfile to include more modern object pascal specific functions, etc. I also have a wordfile for Delphi forms, in case you want to edit the text version of one of your forms.
I'm attaching it for your review, as it isn't on the wordfiles page of IDM.
