(71b) HP41 module programs in HP71b

[Erwin]

First report,

unfortunately, I have no experience with HP41 (HP71b and HP67 only) so I can only use try and error for the data conversion.
I tried to convert the text program of the HP41 navigation program (like the proposal in the post from Didier). TRANS41 converted it without an error, but running the program ends with an error.
So I started with a small HP41 program (I named it VECTOR) to see how it is running. But this ends up with an error too.

This is the small HP41 program:

Code:

01 LBL "MV"
02 1/X
03 X<>Y
04 CHS
05 R^
06 CHS
07 R^
08 1/X
09 P-R
10 X<>Z
11 R^
12 P-R
13 RDN
14 +
15 X<>Z
16 +
17 R-P
18 1/X
19 X<>Y
20 CHS
21 X<>Y
22 END

and here the documentation of the run

Code:

Are there any ideas what happens there?
