Hello, before Mathematica 7 the following command could be used to return the contents of a binary file as a list of records, each record being a nested list of a certain structure, for example BinaryReadList[file,{"Integer32", {"Real64", "Real64"}, "Integer32"}] Mathematica 7 complains: BinaryReadList::format {"Integer32", {"Real64", "Real64"}, "Integer32"} is not a recognized binary format. I know there are other ways (see below one suggestion). But what is the purpose to eliminate useful existing functionality in new Mathematica revisions? Here is my workaround: format = {"Integer32", {"Real64", "Real64"}, "Integer32"}; data = BinaryReadList[file, Flatten @ format]; formats = ConstantArray[format, Length[data]]; positions = Position[formats, _String]; rules = Inner[Rule, positions, Flatten[data], List]; ReplacePart[formats, rules] Best regards, Hannes Kessler
