Many thanks to those who responded to my recent request 
for information on the obsolete Nag subroutine E01ADF.

I now have a copy of the documentation.

Subject: Advance Notice of a Course on Using the NAG Library

         UNDERSTANDING and USING the NAG LIBRARY

This course, based at Oxford University, is being offered again 
this July (July 10-14) after its successful inauguration in December 
last year. It was enthusiastically received by the first course 
attendees as having made an invaluable contribution to their 
understanding and confident use of the NAg Library.

The course consists of 5 days of lectures and practical computing 
sessions covering a major part of the library. The lectures 
emphasise the theoretical concepts that are crucial to the 
effective use of NAG Library routines and these are brought out 
through practical examples in the computing sessions.

Subject areas covered in the course include the solution of systems 
of linear and nonlinear equations, constrained and unconstrained 
optimisation, curve and surface fitting and the numerical solution 
of initial-value and boundary-value differential equations.

For further details please contact:

Dr. A.K.Parrott, UCINA Coordinator, Oxford University Computing 
Laboratory, 11 Keble Road, Oxford, OX1 3QD.

Subject: C Libraries and C


"NAG has a C Library" is a marketing shorthand to draw attention to
the facilities we currently offer C programmers:

1) firstly we have a number of C routines available in source form
at various disparate locations (I have one in my own filestore).

2) secondly we are willing to offer a C translation service to those 
C programmers who need a special Fortran routine translating into C.

[%% C'mon somebody must want E04UAF :-) ]

3) thirdly we are about to announce the availability of C header 
files to facilitate the Fortran library routines to be called from C 
programs with parameter checking.


NAG would be very happy to hear of specific user requests in this 
area. (We have had a request from the British Standards Institute 
for a C version of FPV to include in their validation suite. Would 
anyone else want this ?)

Subject: A book by Chris Phillips and some hanger-on

Those of you who attended NAGUA last year will recall seeing an 
advance copy of
      NUMERICAL METHODS IN PRACTICE
         Using the NAG Library

an excellent book written by Tim Hopkins and Chris Phillips and 
published by Addison Wesley. I commend it to you.

If, like many people who have spoken to me, you have had difficulty 
obtaining a copy of this book you may be pleased to learn that it is 
now available from NAG Ltd at 14.95 pounds plus post and packing.

Subject: Help Systems

It has come to my notice that IMSL has recently released `an interactive
documentation facility' for its mathematical library. According to the
blurb facilities include `easy use, customizing capabilities for the 
individual user, identification of subroutines via keyword search and
GAMS classification, direct output to files, history buffer, review
commands and on-line help'.

My questions

1) Has anyone out there used this system and if so how does it compare
   with the NAG help system?

2) What sort of facilities would users like to see added to the NAG
   help system?

3) Do users actually use the NAG help system and if so for what
   purposes (e.g., just looking up error messages or for serious
   routine selection)?

Come on some of you must have an opinion!

Tim
