**Moon Landing Simulation for the HP41****
****
**

**
I adapted this program for SIM41 from the original HP25 code found in
a page of David G. Hicks. See detailed instructions in that page.

I tried to maintain high compatibility with original HP25 code. The label number used for each label is equal to the corresponding line in the HP25 program code.

My main goal in this translation is to test the behavior of HP25 programs running in HP41 calculators and, of course, in SIM41.
