+% [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.

+@x [38] File opening.
+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.

+% [28] This fixes a bug in the original. If get_byte is reading a
+%      number at the end of a line and the next line has a number
+%      at the beginning (possibly preceded by some spaces!!) these
+%      two numbers are run together.
+%      This bug may be found in other routines so...
+%      Fix: add some (more?) space at the end of each line, in fill_buffer.

+The conversion from control sequence to byte sequence for enc\TeX is

+of string pointers with |hash_size| length, but we assume that only a
+few control sequences will need to be converted. So |mubyte_cswrite|,
+an array with only 128 items, is used. The items point to the token
+lists. First token includes a csname number and the second points the
+string to be output. The third token includes the number of another
+csname and fourth token its pointer to the string etc. We need to do
+the sequential searching in one of the 128 token lists.

+@ Auxiliary functions/procedures for enc\TeX{} (by Petr Olsak) follow.
+These functions implement the \.{\\mubyte} code to convert
+the multibytes in |buffer| to one byte or to one control
+sequence. These functions manipulate a mubyte tree: each node of
+this tree is token list with n+1 tokens (first token consist the byte
+from the byte sequence itself and the other tokens point to the
+branches). If you travel from root of the tree to a leaf then you
+find exactly one byte sequence which we have to convert to one byte or
+control sequence. There are two variants of the leaf: the ``definitive
+end'' or the ``middle leaf'' if a longer byte sequence exists and the mubyte
+tree continues under this leaf. First variant is implemented as one
+memory word where the link part includes the token to
+which we have to convert and type part includes the number 60 (normal
+conversion) or 1..52 (insert the control sequence).
+The second variant of ``middle leaf'' is implemented as two memory words:
+first one has a type advanced by 64 and link points to the second
+word where info part includes the token to which we have to convert
+and link points to the next token list with the branches of
+the subtree.
+
+The inverse: one byte to multi byte (for log printing and \.{\\write}
+printing) is implemented via a pool. Each multibyte sequence is stored
+in a pool as a string and |mubyte_write|[{\it printed char\/}] points
+to this string.

+The conversion from control sequence to byte sequence for enc\TeX is

+of string pointers with |hash_size| length, but we assume that only a
+few control sequences will need to be converted. So |mubyte_cswrite|,
+an array with only 128 items, is used. The items point to the token
+lists. First token includes a csname number and the second points the
+string to be output. The third token includes the number of another
+csname and fourth token its pointer to the string etc. We need to do
+the sequential searching in one of the 128 token lists.

+These functions implement the \.{\\mubyte} code to convert
+the multibytes in |buffer| to one byte or to one control
+sequence. These functions manipulate a mubyte tree: each node of
+this tree is token list with n+1 tokens (first token consist the byte
+from the byte sequence itself and the other tokens point to the
+branches). If you travel from root of the tree to a leaf then you
+find exactly one byte sequence which we have to convert to one byte or
+control sequence. There are two variants of the leaf: the ``definitive
+end'' or the ``middle leaf'' if a longer byte sequence exists and the mubyte
+tree continues under this leaf. First variant is implemented as one
+memory word where the link part includes the token to
+which we have to convert and type part includes the number 60 (normal
+conversion) or 1..52 (insert the control sequence).
+The second variant of ``middle leaf'' is implemented as two memory words:
+first one has a type advanced by 64 and link points to the second
+word where info part includes the token to which we have to convert
+and link points to the next token list with the branches of
+the subtree.
+
+The inverse: one byte to multi byte (for log printing and \.{\\write}
+printing) is implemented via a pool. Each multibyte sequence is stored
+in a pool as a string and |mubyte_write|[{\it printed char\/}] points
+to this string.
