One receipe is to use function wrappers for all relevant ones (without
knowing fpGUI much I think this may be what Graeme did):

1. Write your own string functions wrappers.
2. Use only your wrapper functions in your code.
3. If something changes in the future adapt or rewrite your wrappers,
not the complete source of your programs.

It's the same thing I personally do for floating point types. For
testing I need to have the ability to switch between single and double
or other types. So I define my own general basic float type and switch
it:

type
  //basefloat = single;
  //basefloat = double;
  basefloat = extended;

String are a little more work, but if your wrapper functions are inlined
there will be no problem, even if they do nothing at all.

HTH anyhow,
Marc
