Thread: Function for a string

I need to write a function that will take a string and an int and return the string from index int onward.
for ex

Code:

Line = "Enter a line: ";
WriteString(RetStr(Line,4 ));

//Should return er a line:


//and below is the function

Code:

AnsiString RetStr(AnsiString Str, int Start)
{     int ill;
      ill=1;
      char temp;
      while (Start!=Length(Str))
      {
           temp=Str[Start];
           Str[ill]=temp;
           ill=ill+1;
           Start=Start+1;  
       }
                return Str;
}

I've tried it in several combinations like trying to use a for loop but
Str[ill]=Str[Start+1] gives some errors that i don't know what to make of them.
Please help...
Any pointers will be greatly appreciated
