Look for symbols like _text and _etect (use "nm -n prog.ex" to find them. Their *addresses* demark your program areas, so code like: extern char _etext, _text; ... progsize = &etext - &text; Alternately, declare them as arrays of char and treat them like they *are* your program: extern char _text[];
