     Well, I can't help out much on the programming estimates part (who
honestly can?).  However, as far as the knowledge of UNIX libraries is
concerned, one of the excellent books on C does provide thorough coverage
of this area:

	Samual P. Harbison and Guy L. Steele,
	C: A Reference Manual, 2nd Edition,
	Prentice-Hall, 1987

     Something that may help with the more difficult parts of C for
beginners is:

	Alan Feuer,
	The C Puzzle Book,
	Prentice-Hall, 1982


    Hmm, COBOL???  I remember an absolutely impossible 800 line COBOL
program I once met up with in the seedy IBM world many moons ago......

    That depends upon the individual and their previous experiences.  I 
mean, is C the *only* new element for these people to learn?  Will they
be moving from something like MVS to UNIX as well?  Is there at DBMS
involved?  Is this a new application area for these people?  There are
a lot of factors that can come into play here that are often overlooked.

    We used Plum's book back in late 1983 to start with.  However, we went
through it page by page and classified each item as a must,  a nice practice
but not required or not applicable.  I don't know how up to date the book is
now, but it is one of the few books on the topic.  I would recommend reading:

	Andrew Koenig,
	C Traps and Pitfalls,
	Addison-Wesley, 1989


    This book, while relatively compact, contains a wealth of programming
experience with C.  It has contributions from many experience C programers
from real life experience.


     For programming style, in general, the bible is:

	Brian Kernighan and P.J. Plauger,
	The Elements of Programming Style, 2nd Edition,
	McGraw-Hill, 1978

     The examples are in FORTRAN and PL/1, but are very much applicable
to almost any procedural language.
