I'm not able to reproduce this difference on my DM41X, I've tested both programs.

I'm running DMCP v3.18t03 and DM41X v1.11t08

Srange, same firmware here, what is your hardware version, in settings /selftest/diagnostics in the upper right corner.

Now I have the 41X up and running again I was playing around doing different tests and I discovered the following. Run this very simple program on the DM41X and an original HP41 01 LBL TEST 02 1 03 ST+ 01 04 VIEW 01 05 GTO TEST 06 END On the HP41 it shows a simple increasing counter till you hit R/S...
