wow, you know i think i tried all sorts of combinations of brackets to parse 
things, and i just get different errors.  i think there is something more 
subtle amiss with the interpreter or the syntactical regulations.

..or i had some logical error in some loop nesting.  i converted everything to 
plain numbered variables with plenty of brackets and the code simulation does 
what is expected, but is way harder to read and write, and kind of awkward 
voiced because of first crack guesses on assigning different paRameter regions.

also made an effort to have only one operator per block rather than composite 
expressions.

 I think you need brackets around the
 expression...
 
 http://www.linuxcnc.org/docs/2.5/html/gcode/overview.html#sec:Expressions
 
 So it would be #<_RR>=[#<_DD>/2]
