RPNCALC is an emulation of an RPN type calculator. Suitable for scientific
work in either form although CALC87.COM is recommended for accuracy.
This is release 0.2 so don't expect all the bells and whistles or all of the
answers to be correct. GRADS does not work correctly. ACOSECH is also wrong.

Number enter number function
and Number function
Two physical constants have been omitted from CALC.COM due to lack of precision
of the compiler.
Pre-error checking is only done for divide by zero but it may show up where you
