I like what you are doing here. I'm still stuck on V3R1, but SOME DAY I'll get 
to try it.
I have dabbled with VisualBasic just to see what it's like. One thing that I do 
like is how you can change attributes using keywords. Now that we are removing 
indicators from RPG, what about removing them from display files. Instead of 
conditioning the Position Cursor "DSPATR(PC)" with an indicator, let us use a 
BIF type statement (i.e. %PosCur(Field_Name:RecordFormat) = *On). You could do 
things like positioning cursor, setting the color, underlining, reverse image, 
etc. INDDS will let you set on the indicator with a meaningful name, though you 
will still need to use the indicator in the display file.
