You mean something faster than a for-loop? Like a hash table?
I don't know of any hash table in the standard library but there are some in the class library:

I have not used these myself but they may suit your problem.
Or you can just write your own hash table function. It is not that hard.

is there a function like
if IsOneOf('subtext', ['abc','cde','fecg','hig']) then begin
...
end;
is there such a function IsOneOf(TheSubString : String; const TheStrings
: array of String) : Boolean
?
if yes, what is its name and unit?
