What I'd love to see in one of the next revs: basically the << >> programming of the HP RPN calculators. Have a command that starts RPN programming mode, then simulate the stack operations in the program:

EXPORT NORM

BEGIN

RPNMODE

PUSH * SWAP PUSH * + SQRT

END

Above would take two items on the stack, multiply each by itself (in effect squaring each), adding them together, then taking the square root.

That's RP

*L*. Your example would look as follows in true RPN:

x^2

x<->y

x^2

+

SQRT

RTN

or (without an x^2 function):

ENTER

*

x<->y

ENTER

*

+

SQRT

RTN

IMHO, this way of programming is far easier to read. YMMV.

d:-)

That would be cool to have a keystroke programming language in a graphing calculator.

Yes, I am playing catch up on this forum.

That would work for me too...
