% TEX.MCF: This is the configuration for a standard working TeX 3.14159.
% Place this file into the TEXCONFIG path so that VirTeX and IniTeX can
% find it on startup.

% The following parameters can be changed to extend or reduce TeX's
% capacity.  They may have different values in IniTeX, when creating
% a precompiled format file, and in VirTeX, when starting a production
% run by loading such a format file.  If you delete or comment any
% line beginning with `set', you will get the stated `default' setting.

set memmax 65530 % default 30000.
% greatest index in TeX's internal mem array; must be strictly less
% than max_halfword (1,073,741,823); must be equal to memtop in
% IniTeX, otherwise >= memtop.

set bufsize 2000 % default 500.
% maximum number of characters simultaneously present in current lines
% of open files and in control sequences between \csname and \endcsname;
% must not exteed max_halfword (1,073,741,823).

set errorline 72 % default 72.
% width of context lines on terminal error messages.

set halferrorline 42 % default 42.
% width of first lines of contexts in terminal error messages;
% should be between 30 and errorline - 15.

set maxprintline 79 % default 79.
% width of longest text lines output; should be at least 60.

set stacksize 200 % default 200.
% maximum number of simultaneous input sources.

set maxinopen 15 % default 6.
% maximum number of input files and error insertions that can be
% going on simultaneously.

set fontmax 120 % default 75.
% maximum internal font number; must not exceed max_quarterword (32,767)
% and must be at most font_base (0) + 256.

set fontmemsize 36000 % default 20000.
% number of words of fontinfo for all fonts.

set paramsize 60 % default 60.
% maximum number of simultaneous macro parameters.

set nestsize 40 % default 40.
% maximum number of sematic levels simultaneously active.

set maxstrings 6000 % default 3000.
% maximum number of strings; must not exceed max_halfword (1,073,741,823).

% internal value string_vacancies = poolsize - tex_strings.
% the minimum number of characters that should be available for
% the user's control sequences and font names, after TeX's own
% error messages are stored.  tex_strings has value 24,000.

set poolsize 75000 % default 32000.
% maximum number of characters in strings, including all error messages
% and help texts, and the names of all fonts and control sequences; must
% exceed string_vacancies by the total length of TeX's own strings, which
% is slightly less than tex_strings;
% in order to work with LaTeX, poolsize needs to be increased.

set savesize 2000 % default 600.
% space for saving values outside of current group;
% must be at most max_halfword (1,073,741,823).

set triesize 40000 % default 8000.
% space for hyphenation patterns; should be larger for IniTeX than it is
% in production versions of TeX.

set trieopsize 1000 % default 500.
% space for ``opcodes'' in the hyphenation patterns.

set maxtrieop 500 % default 500.
% largest possible trie op code for any language.

set dvibufsize 2048 % default 100.
% size of the output buffer; internally multiplied by 8.

% Like the preceding parameters, the following quantities can be changed
% to extend or reduce TeX's capacity.  But if they are changed, it is
% necessary to rerun the initialization program IniTeX to generate new
% tables for the production TeX program.  One can't simply make
% helter-skelter changes to the following constants, since certain
% rather complex initialization numbers are computed from them.

set memtop 65530 % default 30000.
% largest index in the mem array dumped by IniTeX; must be substantially
% larger than mem_bot (0) and not greater than memmax.

set hashsize 9500 % default 2100.
% maximum number of control sequences; it should be at most
% about (memmax - mem_min) / 10, where mem_min is 0.

set hashprime 7919 % default 1777.
% a prime number equal to about 85 percent of hashsize.

set hyphsize 607 % default 307.
% another prime; the number of \hyphenation exceptions.
