Re: downloading HO 229 v. 2,0 from HP 49/50 Astronomy Programs list Message #7 Posted by Luiz C. Vieira (Brazil) on 13 Nov 2012, 8:39 p.m., in response to message #6 by Al
Hi, Al;
if you allow me, I'd like to make some considerations about that.
I see some particular reasons that lead HP48/49/50 program writers to convert their codes to System RPL and create libraries instead of user RPL programs and directories. First, after a system memory loss (not the one after removing the batteries) the library contents are not lost (AFAIK it applies to the RPL models mentioned above). Second, as a matter of 'code protection', Sys-RPL libraries need specific applications in order to be created and edited while user RPL programs allow changes that might crippled them if the user decides to change something. Of course, once you want to inspect the code to learn some techniques or to actually improve it, I see no problem at all, provided you aim for this. And third, as the author himself wrote in the readme.txt file: Quote: Version two has been converted to System RPL for much better speed. The conversion to System RPL has also allowed for a slightly better user interface.
Some functionalities allowed with the use of Sys-RPL are not offered in user RPL, hence the consequential improvement.
I hope you read these considerations of mine as references for a fair judgment. I would never try to change your mind about this subject, but I thought I might shad some foreign perspective. Would that be OK?
Best regards.
Luiz (Brazil)
