!   This file is the source for the library DIXCST.  This library
! defines the character conversion tables for all character sets known
! to the DIX string module.
! 
!   These are defined in a library so that an auxiliary program could be
! written which would search the library and print authoritative
! character conversion tables.  Also, putting the definitions in a
! library eliminates the necessity of compiling them every time the
! string module (DIXSTR) is compiled.

!   The edit history/version number information in this file is used
! to build a literal, dix$k_dixcst_version, giving the full version
! information.  Modules that use this library (in particular, the
! DIXSTR module) should make an OWN location called
! dix$g_dixcst_version and initialize it to dix$k_dixcst_version.
! This makes it possible to tell at debug time what version of the
! library was actually compiled against.

%SBTTL 'Character Set Tables (CST)'

!++
! .hl 1 Character set tables (>CST>)
!
!   Each of these tables defines one character set and its translation to the
! String Intermediate (SI) form, and vs.
!
!   The structure prefix for character set tables is CST.
!
!   Each table entry contains the information to go from its index character
! (the character whose code is its index into the table) to the proper SI
! character, and from an SI character (used as an index) to the appropriate
! character of the character set defined.
!
!   The SI form is ASCII for the printing characters and formatting controls.
! The other positions are arbitrary.

! .hl 1 Mechanism of definition
! 
!   The full details of the mechanism used in defining CST's are
! complicated.  This scheme was adopted because it is extremely
! powerful, and because the work of adding a new character set
! definition is very simple if approached in a cook-book fashion
! (recipes below).
! 
!   However, the price of this is that the mechanism is non-trivial.  If
! the mechanism itself breaks, you will need to understand it.
! Therefore a full explanation of it is included here.  Note, however,
! that if all you want to do is add a new character set, or change a few
! of the existing definitions, you don't need to know the full details.
! 
!   See the module that performs the actual string conversions (DIXSTR)
! for details of how the tables built here are used.
! 
!   Each character set is assigned a name.  This name must conform to
! the rules for BLISS names when appended to the end of a valid BLISS
! name.  Many of the macros used in defining character set tables take
! the character set name as a string literal as one of their arguments.
! It is a very important name.  Each string data type has, as one of its
! defining parameters, the name of the character set used to encode the
! data.  The association between the data types and the character sets
! is made solely in terms of the character set name.
! 
!   To define a character set, the following things must be done:
! .s 1.list 1
! .le;Select the character set name.
! .le;In file DIXCST, insert a definition of a macro DEF_CST_name, where
! "name" is the character set name selected.
! 
!   The body of the macro should consist of a series of calls to the
! macros LOC_DEF_TO_SI, LOC_DEF_TO_TYP, and DEF_SI_AND_TYP.  In all
! three cases the parameter list is the same -- see documentation on
! DEF_TO_SI or DEF_TO_TYP below.  LOC_DEF_TO_SI defines a conversion
! from the character set to SI.  LOC_DEF_TO_TYP defines a conversion
! from SI to the character set.  DEF_SI_AND_TYP does both.
! .le;After the definition of DEF_CST_name, place a call to COUNT_CST
! giving the name of the character set as the argument.
! .le;In file DIXSTR, place a call to BUILD_CST giving the character set
! name as the argument.  This expands to the actual conversion table.
! .end list
! 
!   In defining DEF_CST_name, be sure to include a conversion from SI
! >SI$K_INVALID>.  This is the SI code that will be presented if the
! source contains some invalid character. 
! 
!   The reason for the two "LOC" macros is as follows:  In the library
! pre-compilation of DIXCST, the DEF_CST_name macros are expanded once
! to find the maximum type and SI characters present in the table.  In
! the compilation of DIXSTR, the DEF_CST_name macros are expanded again
! to build the actual table initialization information.  These two
! different effects are obtained from expanding a single macro by
! establishing different defintions of the "LOC" macros in the two
! situations.  (DEF_SI_AND_TYP simply calls both "LOC" functions, so it
! needs no LOC definition).
