The first response above is the same example I based my update on. Yes I had updated the include file. My change did compile, I just wasn't convinced it was correct. Yes the argument count was where I was having issues, does this necessitate changing all the calling programs? I was trying to work my code around that. I did spot the wiki example. In that they seem to just use a count as the first parameter. I did find one example in my source files that matched that, so at least one example would be straight forward to update.
