Hugh's RPN replacement calculator, RECKON, for the Casio Slim (or FX-9860g)prompted me to finally get one, and I must say I'm impressed with the calculator and with RECKON. However, the SDK has me a bit buffaloed right now, so I haven't begun to create my own Add-in replacement. I also have to say a big thanks to Nigel for posting his RPN replacement, CasioRPN. This will certainly help me understand the "C++" coding for the calculator a bit more, and may prompt me to attempt to write one.

Since this is my first Casio (after using 20 HP's over the last 30 years) I went about creating my usual vector analysis program (something I have on several hp's) which does norms, dot and cross products, projections, additions, and angle between vectors, along with some simplistic error checking. I though this might help me understand the little bugger a bit more.

For those with the Casio slim and a desire for it to do some vector calculations, here's my little attempt at programming. I think it should be self-explanatory.
