I can't even get past the simple sum of numbers in tutorial 1. I keep getting a red X with Error: Syntax Error. :-(

If you are in RPN mode, you need to enter: 'SUM(A!:A6)'
leaving off the = sign and in single quotes.

That was it. Seems silly to me that inside an app you would have to do this but I'm sure there is a reasonable reason for it...

Thanks!

Indeed, there is. At its most basic level, RPN is all about immediate evaluation on entry. Provided you want to SAVE an algebraic expression then, how would you create a formula object in RPN?

The solution they came up with quite a while back (28S/C I think???) is that you have a QUOTE operator that prevents evaluation. To make it simpler, they used ' ' around something to mean quote. Thus in RPN you can do something like 'Y=X+2' and create a formula (algebraic object). It sees the ' and says "Aha. The user wants me to not evaluate the next stuff until I reach a closing ' mark".

When creating the spreadsheet, we wanted you to have the ability to user RPN in there if so desired. Thus any time you are trying to store the FORMULA rather then an immediate evaluation we used the same syntax.

All you are really doing in a spreadsheet with the =A1+B3 or similar is creating a formula you'd like stored in that location. Since RPN already had the syntax for this... we felt we really should use it.

I didn't even think about RPN mode when using the spreadsheet. I am assuming that people are in Algebraic mode since it is closer to computer spreadsheet programs.

Wish list for the Spreadsheet App:

1. Sort Function. Sort columns or blocks of data using any column as an anchor.

2. The ability to convert spreadsheets between HP Prime format to .csv files in the Connectivity Kit.


I am working on my second batch of tutorials this week.

I'm looking forward to them. I found your spreadsheet tutorials very helpful.

Eddie,

You might consider copying these items into your first post in this thread so that they are all available in the same place.

Thanks for your tutorials!

I would prefer the ability to import/export a spreadsheet to/from a CSV-formatted Note to be available on-Prime, not just in the CK. Of course a user program could be written, but it would be convenient to just call a procedure.

Eddie:

How about doing a tutorial on external referencing methods for customizing a spreadsheet?

For example: Referencing Cell(0,0) Sheet definitions, where an optional third number relates to specific parameters, i.e, Cell(0,1,2):="Column A Titlename", Cell(0,2,2):="Column B Titlename", etc.

Sometimes the tutorials are particularly useful, when the help files seem too compressed to get at needed information quickly.

I struggled with this too and found it was simpler just to switch modes to ALG for the simple purpose of working with the spreadsheet app. Subjectively speaking, it's a bit tedious and if I had my druthers, one could use exactly the same notations in the app irrespective of RPN vs. ALG -- fewer conventions to have to master.

Awesome tutorial, thanks for sharing! I had no idea how to use the spreadsheet in my Prime until I watched your tutorials.
