RE: hp 28s - creating nested lists
? It works for me.
When you say the code has errors, does it not compile or does it not run? Does the 28 have a FOR .. STEP statement? If not, then you can't use this version and will have to stick to one of the two others. (I don't have a 28) If it compiles, then you must've entered a typo.. NDUPN is a useful little subprogram.. I always try to make 'beautiful' code, ie. short yet clear, and this way it's both ;-) And perhaps NDUPN can be used elsewhere?

RE: hp 28s - creating nested lists
It compiles, but as written it gives an error message about a bad 'FOR statement.' I checked for typos.
The reference manual shows the HP 28 FOR/STEP statement as: start finish FOR name loop-clause increment STEP increment must be a real number. For example: Code: 1 11 FOR x x SQ 2 STEP |

RE: hp 28s - creating nested lists
Aha.. that's probably it.
The 48/49 STEP syntax specifies: Quote:If the argument of STEP is an algebraic expression or a name, it is automatically evaluated to a number.But the 28 accepts only a real number, not a variable holding one. So, just add EVAL before STEP (or even better, before DUP). That should do it. Code: \<< Cheers, Werner 41CV†,42S,48GX,49G,DM42,DM41X,17BII,15CE,DM15L,12C,16CE |

Edit: The True/False objects in the IFTE statement should be program objects on the 28.

RE: hp 28s - creating nested lists
Then you might as well write it as a normal IF THEN ELSE statement
Code: IF DUP 0 < 7.5 bytes shorter 41CV†,42S,48GX,49G,DM42,DM41X,17BII,15CE,DM15L,12C,16CE |
