Tab does just that.. solves the function in current box and moves to next.
I was a code geek in a prev life. but that was 35 yrs ago. :) I did come out of hiding for Y2k to solve some govt problems with fortran and Ada, Modula 2 and Pascal. All the logic is still there, I would have to relearn all my syntax though. I do mostly M.E. now and proof it out on the CNC.
