HP 33s programs compatible with HP 35s Message #1 Posted by Howard Boardman on 23 July 2007, 1:26 a.m. Are programs for the two calculators interchangeable?

Re: HP 33s programs compatible with HP 35s Message #2 Posted by Namir on 23 July 2007, 9:46 a.m., in response to message #1 by Howard Boardman Howard, My first guess is that the HP-35s should be able to run most if not all HP-33s programs. The reverse is not true especially if the HP-35s program uses the indirect addressing feature, step-numbered GTO and XEQ statements, and so on. One can deliberately write HP-35s programs that are void of new features and make them compatible with the HP-33s. This makes sense if you only have an HP-35s at hand and you need to write a program for someone else who only has the HP-33s. So the bottom line is: Yes and No ... depending on the features used in the HP-35s. Namir
