-% Change file for BibTeX in C, originally by Howard Trickey.
-%
-% 05/28/84 Initial implementation, version 0.41 of BibTeX
-% 07/01/84 Version 0.41a of BibTeX.
-% 12/17/84 Version 0.97c of BibTeX.
-% 02/12/85 Version 0.98c of BibTeX.
-% 02/25/85 Newer version 0.98c of BibTeX.
-% 03/25/85 Version 0.98f of BibTeX
-% 05/23/85 Version 0.98i of BibTeX
-% 02/11/88 Version 0.99b of BibTeX
-% 04/04/88 Version 0.99c; converted for use with web2c (ETM).
-% 11/30/89 Use FILENAMESIZE instead of 1024 (KB).
-% 03/09/90 `int' is a bad variable name for C.
-% (more recent changes in the ChangeLog)
-
-% [0] Let bibtex.tex work with latest webmac (which defines \ET, hence
-% making E active loses).
-@x
-% Note: WEAVE will typeset an upper-case `E' in a PASCAL identifier a
-% bit strangely so that the `TeX' in the name of this program is typeset
-% correctly; if this becomes a problem remove these three lines to get
-% normal upper-case `E's in PASCAL identifiers
-\def\drop{\kern-.1667em\lower.5ex\hbox{E}\kern-.125em} % middle of TeX
-\catcode`E=13 \uppercase{\def E{e}}

-
-% [2] `term_in' and `term_out' are standard input and output. But
-% there is a complication: BibTeX passes `term_out' to some routines as
-% a var parameter. web2c turns a var parameter f into &f at the calling
-% side -- and stdout is sometimes implemented as `&_iob[1]' or some
-% such. An address of an address is invalid. Therefore, we define
-% variables `standardinput' and `standardoutput' in openinout.c.

-@^system dependencies@>
-@:PASCAL H}{\ph@>
-The \ph\ compiler with which the present version of \TeX\ was prepared has
-extended the rules of \PASCAL\ in a very convenient way. To open file~|f|,
-we can write
-$$\vbox{\halign{#\hfil\qquad&#\hfil\cr
-|reset(f,@t\\{name}@>,'/O')|&for input;\cr
-|rewrite(f,@t\\{name}@>,'/O')|&for output.\cr}}$$
-The `\\{name}' parameter, which is of type `\ignorespaces|packed
-array[@t\<\\{any}>@>] of text_char|', stands for the name of
-the external file that is being opened for input or output.
-Blank spaces that might appear in \\{name} are ignored.
-
-The `\.{/O}' parameter tells the operating system not to issue its own
-error messages if something goes wrong. If a file of the specified name
-cannot be found, or if such a file cannot be opened for some other reason
-(e.g., someone may already be trying to write the same file), we will have
-|@!erstat(f)<>0| after an unsuccessful |reset| or |rewrite|. This allows
-\TeX\ to undertake appropriate corrective action.
-
-\TeX's file-opening procedures return |false| if no file identified by
-|name_of_file| could be opened.
