   To download advanced-EFA package Hyball or data-simulation package
   Gendata from the Univ. of Alberta Psychology Dept. http website:

  1.  Using browser Netscape or Explorer (others should also work), go to

                http://web.psych.ualberta.ca/~rozeboom/

      (Don't omit the trailing " ~rozeboom "; you can't easily get there
      from the home page.)  You will see HYPAK.EXE and  GENPAK.EXE listed
      there, preceded by a useless question mark.  First click on your choice
      of these with your right mouse button, next on the "save link as ..."
      (Netscape) or "save target as ..." (Explorer) option in the pop-up menu
      that appears, and proceed from there as appropriate.  (For a 28KB modem,
      download should take roughly 25 minutes if by phone line.)  Left
      clicking may also work; but if your browser interprets left-click as
      a command to run the file, the results will be disconcerting.  But no
      no harm will insue; and if this occurs, exit the site and try again.

      2.  Exit your browser and transfer the download file to the directory
      you have created for holding the Hyball and/or Gendata programs ("GEN"
      or "HYBL" is a convenient name for that if nothing better occurs to
      you).  HYPAK.EXE and GENPAK.EXE are self-extracting ZIP-files that you
      unpack by left-clicking on them in Windows or, if running in DOS, by
      entering " HYPAK " or " GENPAK "at the DOS prompt.  This will release
      a collection of files, one of which is ASCII textfile README.TXT (in
      HYPAK) or READ_1ST.TXT (in GENPAK) which will overview the other files
      in this package.

         If your download is GENPAK, after reading READ_1ST.TXT (which
         you may want to revisit occasionally) turn to SIMDATA.TXT,
         this package's main documenation, for detailed guidance on how
         to use these programs preceded by the theory, both computational
         and model-theoretic conceptual, on which they are grounded.
         Hyball's main documentation is in README.TXT.

      You can read READ.1ST, READ_1ST.TXT, and all the other textfiles
      (extensions TXT and FOR) in Windows Notepad as well as any DOS editor;
      but all the production programs (extension EXE) run in DOS, either
      stand-alone or a DOS window that you should expand to full-screen size.
      To run any EXE-file, type its basename at the DOS prompt in the
      subdirectory you want to collect the production results and hit Enter.
      If the program needs input created previously, files containing that
      must also be in this subdirectory.
