HP 33s programs compatible with HP 35s



#5

Are programs for the two calculators interchangeable?

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.

Not if you use indirect addressing to look at A to Z.

I have submitted a longer post about this.

Good point!
