A question about "split"

susi · August 7, 2021, 2:21pm

So I want it tells me there is no "6"
In real application, I split the string many times, when an error occurred, I don't know which is not exist

That's why selecting 2nd item throws error.

Check list length.
If greater than 1 then it means that particular item exists else not.

He did it as shown in the first post, but he doesn't like this solution, he wants a different one.
But I also think that the method will be the best there. You can also select it, make a procedure that will check the lists. Then it can be used in many places.

Besides, maybe it can be solved in a completely different way, we would have to know the author's intention.

I am ...

OK I rewrote it!
Is it better?

I have a lot to rewrite

susi · August 7, 2021, 3:16pm

You mean here?

Or there is another way...?

Write what do you need? Do you want to search for text in a list or in a string?

susi · August 7, 2021, 3:42pm

string=123456789
need after "2"
→string=3456789
need after "5"
→string=6789
need before "8"
→string=67→what I need

Today one of "2","5","8" is changed (or all of them changed)
I need to know which, or I have to check many times

Thank you Patryk_F

When I find "2"(index2), "5"(index2), "8"(index1) in "123456789"
It works → 67
When I find "2"(index2), "0"(index2), "8"(index1) in "123456789"
It works → ERROR IN BLOCK 0, NO INDEX 2
But when I find "2"(index2), "5"(index2), "0"(index1) in "123456789"
It shows → 6789
It don't know "8" has been changed

When index 1, there is still a little problem

Thank you Juan_Antonio

When I find "2"(after), "5"(after), "8"(before) in "123456789"
It works → 67
When I find "2"(after), "0"(after), "8"(before) in "123456789"
It shows → Not contain
I need it to tell me "5" has been changed
I tried to replace "Not contain" with "No (get at)"
It shows → No 8 (not No 0)(because "8" is the last )

When you write:

"2"(after), "0"(after), "8"(before) in "123456789"

what should you get?

susi · August 8, 2021, 10:10am

Oh, sorry, I was wrong
"I need it to tell me "5" has been changed" is incorrect
Anyway, when I write:"2"(after), "0"(after), "8"(before) in "123456789"
I need an alert: "There is no 0"
