Check if a string contains a word/sentence etc in Turing

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

How do I check if a "get x" has a specific word/sentence in Turing? Is it possible in Turing? In java it's myString.contains(string[, separator]); how how would I do this in Turing? Thanks in advance.

You can do it, you just have to make the .contains procedure.

It would look something like

[code]fcn contains (word, lookingFor : string) : boolean
     for i : 1 .. length(word)
     if word (i) = lookingFor then
        result true
     end if
end for
result false
end contains

var s : string := "Hello World"
put contains (s, "o") 
[/code]

Oh yes, I forgot about index. But the Turing index function is terrible considering it stops at the first occurrence of what you are looking for, and doesn't provide a way to look for more occurrences.

That would be why I do not use index.

Considering that #contains() returns a boolean value, I don't see how this is a problem.

Not to OT, but:

Not saying it matters in this scenario (or in comparison to #contains() in java)

On the flip side, to the OP, Tony is correct about index being a valid and most likely superior way to solve your problem.
