Thank you very much.
Are there any ways by using BAS module ?
So sorry, I'm no coding skills

@linagoode1 either use a third-party module (install it) or use the code

Yes, i tried it. It's great!
But I am not success.

When a variable value is a string "A1",
I want to check "A1" is or not in a file.
I have set the file as a resource.

when the file doesn't have "A1", the result is false,
but when the flie has "A1",the result is still false.
