I am interested in learning how to program with my hp48gx. I already know a few commands but I really want to make my own games. I have the advanced users manual but I still think I need a little more help understanding it. What is the best way to learn how to program? How should I do it? Thanx.


I would normally suggest trying HTTP://WWW.HPCALC.ORG but today my DNS can't see them. I hope it's just a transient problem for me and that they haven't gone away...


I had the same experience today and I checked where the availability check engine stated, that the domain would be available.

Correction: I re-checked just 5 hours later and found, that the domain is reserved now.

1st check: 22:00 middle-european time 2nd check: 03:00 middle-european time (now)

I consider that as a bad (or at least suspect) sign.

Does anybody know, who could be reached to ask him about the site ? The server still doesn't have a DNS entry

The Internic whois search gave me the following text:

Domain Name: HPCALC.ORG


Whois Server:

Referral URL:



Name Server: NS1.HPCALC.ORG

>>> Last update of whois database: Fri, 14 Jan 00 01:56:51 EST <<<

Maybe they just changed the server ?


Eric recently changed the IP address of his site and hasn't been able to get the DNS changed yet. Until he does, you can still get to through this alternate link:


You can also get to by


Step 1: Order an HP-48 Advanced User's Reference from an HP dealer or mail order supplier. You really can't get far without it.

Step 2: While you're waiting, there are some quite good tutorials at the site.

Look for any text files by Joe Horn - I remember reading one from him about the HP28 that helped me get my head around RPL, and another excellent one on user-defined functions that made things a lot clearer.
