[TI-BASIC] I sound noobish...

Is there a limit to how many nested 'If-Then's you can have in one?

Example:

Code: Select all

If K=92:Then
If L=23:Then
If A=2:(execute code)
End
End

[Xphoenix]

Nope. No limit. But your instance above, if that is your code, could be

Code: Select all

If K=92 and L=23 and A=2
(execute code)

You can use multiple 'And' statements?

[Xphoenix]

Multiple or, and ,not(, xor, whatever.

You can also use combinations, like

Code: Select all

If X=Y or X=Z and A=B or A=C

But remember the priority ladder (that's what I call it).

and comes first, then or, then xor. So

Code: Select all

If A=B or A=C and B=C

would be like

Code: Select all

If A=B or (A=C and B=C)

but you save a few bytes by excluding the parenthesis.

-------------------------------------------

So if A=1, B=2, and C=1,

Code: Select all

If A=B or A=C and B=C

(A=B)=0
(A=C)=1
(B=C)=0

Code: Select all

If 0 or 1 and 0

(1 and 0)=0
(0 or 0)=0

So that would evaluate to 0, or false.

Slightly confused, but okay. Thank you.

I might have included too much stuff in my post above. The only important thing is the stuff above the line a typed.
