A couple of changes to the TI-NSpire programming language, including the addition of a host of commands and libraries, and the Request "x",y command, have made the programming experience more pleasant on the Nspire. Finally, something that comes a giant step closer to behaving like a normal programming language. The language appears to be undocumented as of 2010.
The assignment command using “STO>” doesn’t work the way it used to, but I wasn’t aware that the Nspire had a Pascal-style “:=” for variable assignment.
The spreadsheet could be populated once, but re-running the program to populate the spreadsheet with different data lead to the Nspire becoming confused, and garbage data winding up on the spreadsheet. Deleting the spreadsheet, and re-inserting the array names once more on the tops of the columns resulted in the new array values updating themselves automatically on the spreadsheet.
There needs to be a way to declare and name a spreadsheet programmatically, and I don’t see a way yet. There also needs to be a way of disposing of the spreadsheet or clearing a spreadsheet, inside of the program. Again, I don’t know of a way to do that yet.
Once I get the code perfected a little more, I’ll post it.
