Porting 49G Programs to 49G+/50G



#2

Under what circumstances do 49G programs not run in the newer calculators?

I have located a lovely little library at HPCALC.org that performs the simplex algorithm that works well in the Power48 on my Palm using ROM Revision 1.19-6 but fails on my 49G+ using revision 2.09.

I really thought that the 49G+ and 50G were essentially the same calculator as the 49G and there should be fairly seamless cross-compatibility of programs. I really don't want to revert to an old ROM to use this program!

Many thanks,

Les


#3

If supported entries were used, they should work just fine.

The only things that tend to cause trouble is display size and SD access. Which library is it (link)?

#4

http://www.hpcalc.org/details.php?id=4255


#5

It seems to work fine on mine running through all the commands. Do you have a specific thing that fails, or do all of them? Perhaps it was transferred wrong?

TW

#6

I got it to work on a simpler and smaller program in the (limited) documentation.

Don't know why the first problem I tried failed.

Les


#7

Found it.

The data matrix needs to be in a certain form. I mistyped the example and the program rejected it. There is nothing wrong with the library. It runs just fine on the newer calc with the most recent ROM.

Les


#8

Good to know.

TW
