I have corrected the listing in post #5 about half an hour before you wrote your reply. Maybe you have entered the (erroneous) original listing. There have to be three NOPs that I originally forgot to include.

The HP67 skips one step after a false test, while the HP65 skips two. So the program cannot be directly used on the HP67. However, an adapted version works fine on the HP67 – that's the calculator on which I tested the program. ;-)

Here is an HP67 listing:

Code:

LBL A
STO 1
0
x!=y?
RTN
RCL 2
RCL 2
RCL 3
*
EEX
2
/
-
STO 1
RTN
LBL B
STO 2
0
x!=y?
RTN
RCL 1
1
RCL 3
EEX
2
/
-
/
STO 2
RTN
LBL C
STO 3
0
x!=y?
RTN
1
RCL 1
RCL 2
/
-
EEX
2
*
STO 3
RTN
LBL E
FIX
DSP 2
CLX
STO 1
STO 2
STO 3
RTN

But on the HP67 I would prefer a different approach using the data entry flag 3.
