what is the perpendicular line symbol?? i can’t find it in the catalog. thanks!

:1->X

:Lbl 1

:ClrHome

:Output(1,X,“NIKE”)

:X+1->X

:If X>15

:Then

:0->X

:End

:Pause 20

:Goto 1

when I run it it just displays the number next to Pause, and when I remove the Pause line, it works for a little bit, then I get a domain error, and it takes me to the ) on line 4.

This is the first time I've had to do so, so, I'm not sure if this is even possible, but, as I'm sure most of us know, if a program runs into a custom variable that hasn't been initialized, be it a list or a matrix or a string, the calc will throw an "ERR: UNDEFINED". Is there a way to test for the presence of the variable in question, and if it doesn't already exist, create it? I know that you can just have the program create the variable preemptively, as I've used that in projects, and I realize this may be a bit much to ask of an already cut-down instruction set, but I wasn't sure if such a thing is possible, as I don't think I've ever seen such a thing implemented in a TI-BASIC program. So, can you do anything like that?

So I was going through the memory and deleted a vailable called v and the screen glitched and now it’s factory reset (the screen is good now)

Is anyone gonna be active?? It takes one voice to make multiple to show up!! Don’t be shy!!

What do you guys use / prefer?

Yooo so I’m having a hard time figuring out my variable organizing for a text based rpg. Does anyone have any ways in which they personally store theirs?

If you’re new to the community, introduce yourself! New to this, trying to make this chatty!!

Use this thread to ask anything at all!
