Going from NAV 2009 R2 to Beta we can observe that quite some FIND ('-') and FIND('+') had been replaced by FINDFIRST and FINDLAST and from Beta to RTM almost the same number of replacements. Some additonal math shows us that almost half of all FIND('-')/FIND('+') has been replaced by FINDFIRST/FINDLAST (more exactly 44%).
Note that the relative occurences of most other variations of FIND() did not change (see the next graph).
Haha, I was wondering anybody would ask, or at least wonder about this. You know this didn't cost me a lot time to be honest. If it would have, I wouldn't have done this at all. In a way I am a workaholic, but, hey, I am also somewhat lazy, otherwise I wouldn't have end up in this business.
Recall my posts on FIELDERROR and also on the findfunc cmd line tool?
It's the same trick and very efficient once I did have an Excel sheet setup to accept the data in reformat them for me to get these statistics out.
