In my program I have 2 different menus. After each menu can I use the same Label to call a value from a list?

At the top of my program I have a list:
.00024->A
There are many other items here but I only need one for my example.

Then on my 1st menu I have:
Menu("TEST","ALUM",A, and so on)
Lbl A
A->Y
GoToC

Then I have:
Lbl C
Menu("TEST 1","ALUM",L, and so on)
Lbl L
A->Z
GotoD

I want to add more options to my list so I'd like to be able to get L back so I was wondering if I could replace the "L" in my Test 1 menu with "A" like my Test menu without causing any problems?

I don't have my 84 with me or I would just make the change and try it.

Thanks.

When the program goes to a label, it will always go to the first occurrence of the label in the entire program. Therefore duplicate labels further down in the code will be useless.

I wasn't sure if it only searched forward or from the beginning. I do quite a bit of Macro programming on our CNC machines and they only search forward, but it is typically frowned upon to duplicate any GoTo's's.

Still have a lot to learn programming in Basic. Now I need to get around only having 27 variables to store data to. My program itself uses 10 or so variables in just the math section, and I already have 14 values that need to be stored as well with the way my current program is written. Thought I could use a table/s, but it doesn't look like they function as I thought they did. Need to do some more reading on them.

Anyways, thanks for the help.

If you have a lot of variables, you can indeed use a list (aka array) instead. There's quite a bit of cool things you can do with them, but are generally pretty straight forward. This page should at least get you started: http://tibasicdev.wikidot.com/l

If you have more questions, let me know; I'm happy to help!
