I had not checked it but I think you can use the typecasting:

move(somepchar^,pchar(ansi_str_dest)^,len);

as typecasting an ansistring to a pchar should return (repeat "I
think") a pointer to ansi_str_dest[1], and if length(ansi_str_dest)=0
then the pointer should be $00000001 :-? which should not raise any
kind of range check.
