Hi Andrew,

Sorry I didn't spot this the first time round:

You get a much better regression test by checking for an exact match of 
the output.  Only retval2==-1 will make the above test fail.  What about 
-2?  Assuming retval2 should be zero, how about:

ok(retval2==0,"Failed to add String to String Table\n")

> +    ok(retval=retval2,"string and String have different IDs in String Table\n");        

Did you mean to use == here?
