% For Nuclear Science and Engineering
% Changes made by Paul K. Romano to match style for Nucl. Sci. Eng.
% Sep. 19, 2010
% - Added FUNCTION quote and used on format.title
% - In FUNCTION article, added title
% - Emphasized journal name in FUNCTION article
% - changed FUNCTION format.names to make author names all caps
% Feb. 13, 2012
% - Removed "Technical Report" prefix
% - Year for technical report in parentheses
% Jun. 29, 2012
% - Changed format.title to preserve capitalization
% version 0.99b for BibTeX versions 0.99a or later, LaTeX version 2.09.

ENTRY
% Fields:
{ address
% Usually the address of a publisher or other type of organization.
% Put information in this field only if it helps the reader find the
% thing---for example you should omit the address of a major
% publisher entirely. For a PROCEEDINGS or an INPROCEEDINGS,
% however, it's the address of the conference; for those two entry
% types, include the publisher's or organization's address, if
% necessary, in the publisher or organization field.
% annote
% Long annotation---for annotated bibliographies (begins sentence).
author
% Name(s) of author(s), in BibTeX name format.
booktitle
% Book title when the thing being referenced isn't the whole book.
% For book entries, the title field should be used instead.
chapter
% Chapter (or section or whatever) number.
edition
% Edition of a book---should be an ordinal (e.g., "Second").
editor
% Name(s) of editor(s), in BibTeX name format.
% If there is also an author field, then the editor field should be
% for the book or collection that the work appears in.
howpublished
% How something strange has been published (begins sentence).
institution
% Sponsoring institution of a technical report.
journal
% Journal name (macros are provided for many).
key
% Alphabetizing, labeling, and cross-referencing key
% (needed when an entry has no author or editor).
month
% Month (macros are provided).
note
% To help the reader find a reference (begins sentence).
number
% Number of a journal or technical report, or of a work in a series.
organization
% Organization sponsoring a conference (or publishing a manual); if
% the editor (or author) is empty, and if the organization produces
% an awkward label or cross reference, you should put appropriately
% condensed organization information in the key field as well.
pages
% Page number or numbers (use `--' to separate a range, use `+'
% to indicate pages following that don't form a simple range).
publisher
% Publisher name.
school
% School name (for theses).
series
% The name of a series or set of books.
% An individual book will will also have it's own title.
title
% The title of the thing you're referred to.
type
% Type of a Techreport (e.g., "Research Note") to be used instead of
% the default "Technical Report"; or, similarly, the type of a
% thesis; or of a part of a book.
volume
% The volume number of a journal or multivolume work.
year
% The year should contain only numerals (technically, it should end
% with four numerals, after purification; doesn't a begin sentence).
}
% There are no integer entry variables
{}
% These string entry variables are used to form the citation label.
% In a storage pinch, sort.label can be easily computed on the fly.
{ label }
% Each entry function starts by calling output.bibitem, to write the
% \bibitem and its arguments to the .BBL file. Then the various fields
% are formatted and printed by output or output.check. Those functions
% handle the writing of separators (commas, periods, \newblock's),
% taking care not to do so when they are passed a null string.
% Finally, fin.entry is called to add the final period and finish the
% entry.
%
% A bibliographic reference is formatted into a number of `blocks':
% in the open format, a block begins on a new line and subsequent
% lines of the block are indented. A block may contain more than
% one sentence (well, not a grammatical sentence, but something to
% be ended with a sentence ending period). The entry functions should
% call new.block whenever a block other than the first is about to be
% started. They should call new.sentence whenever a new sentence is
% to be started. The output functions will ensure that if two
% new.sentence's occur without any non-null string being output between
% them then there won't be two periods output. Similarly for two
% successive new.block's.
%
% The output routines don't write their argument immediately.
% Instead, by convention, that argument is saved on the stack to be
% output next time (when we'll know what separator needs to come
% after it). Meanwhile, the output routine has to pop the pending
% output off the stack, append any needed separator, and write it.
%
% To tell which separator is needed, we maintain an output.state.
% It will be one of these values:
% before.all just after the \bibitem
% mid.sentence in the middle of a sentence: comma needed
% if more sentence is output
% after.sentence just after a sentence: period needed
% after.block just after a block (and sentence):
% period and \newblock needed.
% Note: These styles don't use after.sentence
%
% VAR: output.state : INTEGER -- state variable for output
%
% The output.nonnull function saves its argument (assumed to be nonnull)
% on the stack, and writes the old saved value followed by any needed
% separator. The ordering of the tests is decreasing frequency of
% occurrence.
%
% output.nonnull(s) ==
% BEGIN
% s := argument on stack
% if output.state = mid.sentence then
% write$(pop() * ", ")
% -- "pop" isn't a function: just use stack top
% else
% if output.state = after.block then
% write$(add.period$(pop()))
% newline$
% write$("\newblock ")
% else
% if output.state = before.all then
% write$(pop())
% else -- output.state should be after.sentence
% write$(add.period$(pop()) * " ")
% fi
% fi
% output.state := mid.sentence
% fi
% push s on stack
% END
%
% The output function calls output.nonnull if its argument is non-empty;
% its argument may be a missing field (thus, not necessarily a string)
%
% output(s) ==
% BEGIN
% if not empty$(s) then output.nonnull(s)
% fi
% END
%
% The output.check function is the same as the output function except that, if
% necessary, output.check warns the user that the t field shouldn't be empty
% (this is because it probably won't be a good reference without the field;
% the entry functions try to make the formatting look reasonable even when
% such fields are empty).
%
% output.check(s,t) ==
% BEGIN
% if empty$(s) then
% warning$("empty " * t * " in " * cite$)
% else output.nonnull(s)
% fi
% END
%
% The output.bibitem function writes the \bibitem for the current entry
% (the label should already have been set up), and sets up the separator
% state for the output functions. And, it leaves a string on the stack
% as per the output convention.
%
% output.bibitem ==
% BEGIN
% newline$
% write$("\bibitem[") % for alphabetic labels,
% write$(label) % these three lines
% write$("]{") % are used
% write$("\bibitem{") % this line for numeric labels
