Also: HP48 is a simplified form of Lukasiewicz's RPN...
i seem to recall that the original RPN was notated something like:
(2,4,+) or (+,2,4) ???
While HP48 RPN is simply 2 4 +
Then: The HP48 also allows for Algebraic notation, so that if you want
to use a conventional ( or nearly so ) Algebraic Equation inside a
program, you can do that...
But surrounding that, you have the very simply RPL notation.
You can also Store things in a conventional manner, and perform STO+
STO- STO* & STO/ operations, which may seem more like 'normal'
programming...
Or you can use The Stack, which may take some getting used to, but, as
you've suggested, once you 'get' The Stack, Storing variables that are
actively being used, is an annoyance...!!!
Also: The great thing about RPL is that it is COMPLETELY FREE of all
the 'Formatting' that many programming languages insist on... You want
to caluclate the Sine Function of 123.456...
On an HP48 the procedure is: 123.456 SIN
and the result is left on the Stack, to be used immediately in the
next operation.
If 123.456 is stored in a variable like 'A'; Then it's: A SIN.
That's it.
No Hidden Craziness or streams of senseless punctuation...
