  17.     I have an information retrieval program written in "c" that I would
  18.     like to convert to a web application.
  19.     The indexing portion of the application generates an inverted file of
  20.     the format:
  21.         word   32-bit integer
  22.         ...
  23.     
  24. To read binary data in Icon:
  25.     -- open the file in "untranslated" mode
  26.     -- read multiples of 4 bytes using reads()
  27.     -- convert characters to binary using ord(), and pack together
  28.     -- or convert using pack/unpack from the Icon Program Library:
