Version 2 of the TI Nspire operating system

My main complaint about the Nspire and Nspire CAS, the need to have some kind of input statement in its programmnig language, looks like it is closer to reality. I just have to fiddle with it some more to see if it can really place data in tables (or now, spreadsheets), and see if I can really do I/O in a running program as was the case for the TI-84 family. To be clear, I am not using the new “touchpad” version of the CAS, I am using the slightly older version, which had the original keyboard.

When I did a test statement

Request "---> ", j
and ran it, the calculator came back with a screen using “–>” as a prompt, and a blank for me to input something. I entered “36”, then the input window disappeared, then the string

--> 36
was output. The input window seems cumbersome.  That could be because I like command line input, and think it has less memory overhead on a device where every byte of RAM is precious.

At any rate, the value is stored in j, and this was proven by doing the multiplication

4j
and I got 144. This was on a calculator whose memory was cleared due to the OS upgrade. The cursor is much more sensitive, and there is a noticeable speed impovement over prior OS versions.

I tried to make a simple program, and got nowhere with the Request statement, when I placed it inside a FOR/END FOR loop in a named program.
