I need to process a line of text using a function that accepts a line of text as a parameter and returns a new processed line of text as a return value. eg.
TextInput                               TextOutput
'45Hello ?there'                     ' Hello there'

I'm not sure what you mean... You can not do that unless you use Pascal... If you think I misunderstood your question, please support some more info, and a more detailed explanation...

Do you mean you want a function that strip all the non-alpha characters (except space) from a string? Below may be a solution:

function myStrProc(InputStr:string);

var
   OutputStr:string;
   i:integer;
begin

     OutputStr:=InputStr;
     i:=1;
     while  i<=length(OutputStr) do
        begin
           if ((Ord(OutputStr[i])>=65) and (Ord(OutputStr[i])<=90) or (Ord(OutputStr[i])>=97) and (Ord(OutputStr[i])<=122) or (Ord(OutputStr[i])=32))then
               i:=i+1
           else
               Delete(OutputStr,i,1);
        end;
        result:OutputStr;
end;
