How to check for any lower case or space in a string

Answer:

1   function ContainsLowerCaseOrSpace(AString: string): boolean;
2   var
3     MySet: set of char;
4     Len, Counter: integer;
5   begin
6     MySet := ['a'..'z', ' '];
7     Len := Length(AString);
8     Result := Len <> 0;
9     Counter := 1;
10    while (not Result) and (Counter <= Len) do
11    begin
12      if AString[Counter] in MySet then
13        Result := True
14      else
15        Inc(Counter);
16    end;
17  end;
18  
19  procedure AddSpaceBeforeUpperCaseCharOrNumber(var AString: string);
20  var
21    Counter: integer;
22    bLastIsNumber: boolean;
23    bLastIsUpper: boolean;
24  begin
25    Counter := Length(AString);
26    bLastIsUpper := False; {Assume the last character will never be an upper case}
27    bLastIsNumber := AString[Counter] in ['0'..'9'];
28    dec(Counter);
29    while Counter > 1 do
30    begin
31      if AString[Counter] in ['0'..'9'] then
32      begin
33        if not bLastIsNumber then
34          Insert(' ', AString, Counter + 1);
35        bLastIsNumber := True;
36      end
37      else
38      begin
39        if bLastIsNumber or bLastIsUpper then
40        begin
41          Insert(' ', AString, Counter + 1);
42          bLastIsNumber := False;
43        end;
44        bLastIsUpper := AString[Counter] in ['A'..'Z'];
45      end;
46      dec(Counter);
47    end;
48  end;
