Note that you need to know which compiler is being used before you can interpret the structs. Note also that the best approach probably also involves a test file so you can quickly see if your code is working right. That said, each of the types involved corresponds to a size and a bit interpreter, and if you had names in one locale for sizes and names in another locale for methods to convert the bits to J form I imagine you could build a "record -> read function" meta function. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
