Hmm - you are right.. although I seem to recall this being a problem in earlier versions (maybe 10+ years ago in the 16b version?) 
Or maybe I'm just thinking of other languages where it is a problem. Still, it's best not to use Var_ID chars in strings. It won't be a problem in this specific example, but consider something like
which produces C4 - a potentially explosive result. Just because a letter preceeds the "$" doesn't mean it won't get interpreted.
I have a picture hanging in my office - a guy using his laptop at a funeral. The caption says "just because you CAN doesn't mean you SHOULD!" Outside of KixGolf, it's a good rule for programming.
ITDaddy: I may come across like a teacher because it's hard to shake 15+ years teaching IT subjects, including Unix and MCSE. As for rocketry, it's a blast, but no where near that expensive. The average rocket costs about $200 to build (parts/paint/epoxy), and flies with a $100 flight computer (records altitude and speed, fires 2 ejection charges for parachute deployment), and my larger rockets sometimes use a $600 avionics package that transmits real-time flight telemetry, including speed, altitude, and GPS location. The motors cost between $30 and $150. All of these costs are one-time purchases of reusable items. Fuel for the motors can run between $2 and $200 per flight for the rockets that I fly, although there are larger rockets that are much more expensive to build and fly. I build in the winter and fly in the summer, rarely spend more than an average of $200/month on the hobby.
