Hi,
I have ported on WP34s a usefull routine from, of course, J HORN.
It is for know increase AND decrease prices.
It is good to see how mutch prices of anything is different for meal or fiscality,
in France governants are absolutely fools ! I give the commentary of J HORN, He speak english best of me.

Code:

LBL D
DELTA%
X<>y
RCL L
X<>Y
DELTA%
X<>Y
DROP
X<? Y
X<>Y
RTN

I sugest you is in YDON, FIX 02, SIZESTACK 4 (Here it is enought).
The minor is negative and always in YDON, that is register Y.
In the commentary I think is a typo, because negative is alway in level one,
not two.

Have a good day.
