A couple of nice ideas What's [beta] and [beta]^x on your keyboard? And what's the pink MOD= up there?

And some nitpicky remarks:

• You're missing two sums (xlny and ylnx) you'll need for L.R.
• I'd move R/S right of trigs. At its present position it looks a bit lost.
• Pink labels?!? Please think about another color.

  Quote:- an unlimited stack, ... A 'FILL' register is used to fill in past the end of the stack so various tasks depending on duplicating T still work.

  Now what is it what you want? :-?

  Quote:- an unlimited stack, meaning I can do without shortcut functions, [2][y^x] behaves the same as [f][x^2].

  I don't see the link. :-?
