Is it possible to declare the bounds when you declare the pointer? Even if that worked, it's not clearly less awkward than using a separate local function, which is not completely unreasonable. Slightly awkward to work with, but it does direct addressing which we can't do for multi-dimensional non-0-based arrays in C (C99 offers direct indexing for runtime-dimensioned 0-based arrays). Jed
