     Dear Mr. Butch,

     Sorry  for  the delay - I was on vacation and had to get caught up
     on other things. I also had to edit  our  documentation  files  to
     make  the  penciled in changes from our documentation so you could
     get fresh documentation.

     Unfortunately I am unable to send you the  sources  to  the  major
     components  of  the FORTRAN II system (FORT, SABR, and LOADER). My
     boss would rather keep control of the sources. However, copies  of
     all  save-image  files and some other goodies are included. If you
     do experience problems with the major components,  please  let  me
     know ASAP and I will take care of it.

     I  assume you got the stuff from Van Zee. I have only a vague idea
     what versions of programs you  have,  so  I'm  sending  you  fresh
     copies. The 4 floppies (and their backups) contain:

     (*) Sources and binaries for our XLIB8 and FTNLIB.
     (*) Complete FORTRAN II system + LIBCAT utility + DIAG source.
     (*) Documentation.

     Our  SABR requires 16K to run. I expanded a bunch of the tables to
     get around some problems that were created  because  our  compiler
     caused some of SABRs tables to overflow.

     Our LOADER reserves an additional page in field zero to handle the
     expanded  external  symbol table. It also automatically references
     libraries that you don't have. Patch locations 100-117 to  contain
     the 6-bit text of your libraries.

     Our FORTK needs 16K for all the features to work.

     The  FORT  documentation contains many references to stuff we have
     here at HRL (extra libraries,  etc.).  Some  are  embedded  pretty
     deep,  so  rather  than  try to edit it, I am giving you the whole
     thing. The FORTX documentation describes some new stuff in FORTX.

     Drop me a line if you have any suggestions or comments.

     Sincerely,



     John Van Essen
