[fpc-pascal]absolute identifier

[ron wilson]

it does work.  i am using it right now.  according to the documentation on
ansistrings (i actually read them) typecasting is designed to do this...  i
could be wrong i guess.

That should not work.

Better do something like:
 SetLength(Str, BufLen);
 Move(Buf, Str[1], BufLen);
  or
  SetString(Str, Pchar(@Buf), BufLen);
