Is there a standard (or failing that a generally accepted) way of naming the various RPN functions using just __alphanumeric__ characters?

For many of the functions this seems straight forward enough (though I many have abbreviated things too much in places..?)

sin -> SIN

sin-1 -> ARCSIN

x<>y -> SWAP (I'm assuming that SWAP is the same as X<>Y)

+ -> ADD

- -> SUB

/ -> DIV

etc

However, there is rather more scope for interpretation when you try to express some other functions without using 'special' characters - particularly when things get ambiguous...

->R -> ??? (Convert to radians)

RAD -> ??? (Select radian mode)

->R -> ??? (Convert polar to rectangular co-ordinates)

R^ -> ??? (Round up)

R -> ??? (Round down)

r -> ??? (Correlation coefficient)

->H.MS -> HMS (?)

X<=Y -> ???

Q -> Q (A bit to short?)

Q-1 -> INVQ (?)

(i) -> ???

I -> ???

X2 -> SQR (?)

/X -> SQRT (?)

10x -> INVLOG (?)

etc etc etc
