Announcing the "Dare 2 Compare", new version of the Total_Rekall

[Ángel Martin]

I think I've come up with an even better function: the "SHUFFLE w/ zero" - meaning you can either input the stack register letters in the prompts (all the way from T to P, i.e. including the ALPHA registers too) - *or* - you can also enter a zero if you want the corresponding register to be cleared.

Examples: the pattern is XYZTL, five prompts: SHFL _ _ _ _ _

SHFL XYZTL does nothing
SHFL X00T0 will clear Y, Z, and L
SHFL ZT0LL will clear Z, move Z to X, T to Y and L to T
SHFL TXYZL does R^
SHFL YZTXL does RDN
SHFL XXXXL fills the stack with X
SHFL LLLLL fills the stack with LastX
etc...

I'm using ALPHA to hold the master string, I don't think it's that bad and besides there's no more room available for other approaches.

a neat function, thanks for suggesting it!
