-- Purpose 
-- Letter style defines the case of a letter. The letter style of a lexical element ( say word Vhdl_leXicoN ) are lower_case ( vhdl_lexicon ), upper_case ( VHDL_LEXICON ), mix_case (Vhdl_Lexicon ) and unchanged_case ( Vhdl_leXicoN ). 
--
-- The procedure vhdl_letter_set_style allows one to change the letter style of a lexical element without recompiling code. The input stream requires the letter_style specification first followed by the source code. The approach allows the operating system language commands to arrange a variety of ways to format source code. 

-- Assumptions and process overview
-- Input:  device = text_io.standard_input;
--         data = letter specification + vhdl (syntax) source code
--          * the exact format of the letter specification is defined by 'is_initializing' of package 'vhdl_lexicon_letter_style'
--
-- Output: device = text_io.standard_output
--         data = text format with specifications defined in the input stream 
-- Suggested use
-- Change the letter_style without recompiling source code. This can be done by using the shell script: vletter_set_style
