HI! Please, how can I generate GLOBAL variables for any TI applications and programs? I mean, quite precisely, that I can achieve the value of a given variable in MULTIPLE, OTHER TI applications (from a program and / or a spreadsheet)! ... Added info: 1. I come from Hungary and my English is very weak ... 2. My "machine" is a TI-nspire CX II-T 3. In fact, I often use an HP Prime G2 "machine" and I really want to 'transfering' to TI too my developed HP applications ! ... 4. I have previously received information that the global variable must be declared in the "MyLib" directory, but the access mode is not clear ... If you can help me, I would really appreciate it!

You can create global variables / functions / constants by using Actions > Library > Public Library. You will then be able to recall item through the catalogue. Try: kzbin.info/www/bejne/poCycn2ZnLiIqtk So if you want a specific value, say (phi) you can simply return the value for phi from your function.

@@TIAustralia First of all, thanks for the quick reply! By the way ... What you wrote to me, I tried months earlier. At the time, it also worked in a spreadsheet application (which I originally made for TI), but NOW it doesn't work in the same application right now ... "Attachment" information: On November 4, 2020, I purchased the TI-nspire CX II-T. The font size did not work even on the day of FIRST USE! ... (Unfortunately, I was so stupid that I didn’t take the machine back to the seller’s store right away ...) FACT: I'm afraid my machine is factory defective! And since there is NO official TI service in Hungary, I don't know if it's worth using the machine yet, or I acknowledge that I have a crappy machine that I bought for almost $ 200, but it's virtually unusable! .. Concluding Note: The HP Prime G2 has a much faster processor than the TI-nspire CX II-T, and HP is much easier to use than the TI because it has a touch screen! This is especially annoying as the TI-nspire CX II-T was launched 2-3 years later than the HP Prime G2! (Of course, my HP machine also has annoying "pediatrics," but it works essentially flawlessly ...)

@@TIAustralia THX! I will be living with the opportunity soon.

after defining f(x), when i tried to calculate f(b+1) it's say variable not defined i guess its recognise b as a variable. what should i do ?

[@TIAustralia]

I suspect you are using TI-Nspire CX II Non-CAS. The non-CAS version will not produce algebraic output, so f(b+1) would be an algebraic expression if 'b' is not defined, hence the error message "variable not defined". On the CAS version you will not get this error message.

yes thanks for yr replied @@TIAustralia
