Hi dear friends,

I was thinking this past night of a function usefull from some HP RPL.

It is : DUP n

For those wich not know what it is, an sample :

assume we have in level one ( or x register) a value that it is 0 or 1 or "n", if it is 0 no copy but a drop is include and this is the important, if it is 1 it is like enter etc.

In WP34s it is not so I do like this :

If I have zero in x : no copy

If I have one in x : I copy , and drop the value 0 or 1.

Then me I do this :

(I combination test and flag) :

.

.

.

register x = 0

CF 00

DROP

FC?C 00

[ENTER]

[ENTER]

.

.

.

And it is as DUP n for 0 or one.

May be you give me what you think of that ?

Good day.
