MapServer CGI >5.0?

Dear MapServer Users,
Please disregard this inquiry. I since found the problem in my CGI file.
I was using MapServer 5.2.0 in one place but accidentally still calling
MapServer 4.99 in another, thus causing the discrepancy in how I needed
to reference parameters in my map file. Still, though, I wonder why
MapServer >5.0 didn't retain the ability to reference parameters in a
hierarchy like "map_scalebar_size" since now I have to go back and
change all of these references in my code to "map_scalebar=size+value"??
Unfortunately, this change makes things so they are not backwards
