Problem with NewFold and setFold commands

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

Problem with NewFold and setFold commands

jeff22 22 Jun 2009 13:14

Using the following code on TI 89 Titanium

Local fd, fx
getFold( ) -> fd
NewFold # fx
<MAIN PROGRAM CODE>
setFold ( # fd )

This works fine, if Exact/Approx mode is set to Auto or Exact.

If set to Approx I get an error “ Indirection string is not a valid variable name ”

As far as I can tell it something to do with the way # changes a string into a variable

I’m wondering why it should cause this error

Thanks
Jeff

I'm a bit confused as to what you're doing there, since the above code will never work. The variable fx is never defined, so #fx doesn't make sense. If you store a folder name to fx first, then it works regardless of the Exact/Approx setting, as it should.

However, there usually isn't a need to have the new folder name stored in a variable, if you know what you want to name the folder. If the folder's name should be fx, then you don't need to put it in the Local command, and you don't need the # on #fx.

Thanks for your reply

Yes, sorry, it is confusing. I seem to have got myself a bit messed up in trying to save variables to temporay folders.

Anyway I think you have answered it.

Is Local a,b,c incorrect for making local variables

should it be done a line at a time
Local a
Local b
Local c

No, several at a time is okay.
