All template definitions, whether text  or  language-oriented,  begin
  with  a  language definition command (DEFINE LANGUAGE) that specifies
  language characteristics.  For example, to define a language, you use
  the DEFINE LANGUAGE command to specify:

          1. The name of your language (DEFINE LANGUAGE).

          2. The file types (/FILE_TYPES) for the language.

          3. The identifier characters to be used in token and
             alias names (/IDENTIFER_CHARACTERS).

          4. The punctuation and delimiter characters
             (/PUNCTUATION_CHARACTERS).

          5. The required and optional placeholder delimiters
             (/OPT, /OPTL, /REQ, /REQL).

          6. The initial text heading for the new file
             (/INITIAL_STRING).

          7. The indentation control for tokens and placeholders
             (/TAB_INCREMENT).

       Example:

             DEFINE LANGUAGE MEMO -
               /IDENTIFIER CHARACTERS = -
               "abcd....XYZ0123456789" -
               /INITIAL_STRING ={memo_template}" -
               /FILE_TYPES = (.MEMO) -
               /TAB_INCREMENT = 4 -
               /OPT = ("[","]") -
               /OPTL = ("[","]...") -
               /PUNCTUATION_CHARACTERS = ".,':*+-/" -
               /REQ = ("[","]") -
               /REQL = ("[","]...") -

  To define a placeholder, you use the DEFINE  PLACEHOLDER  command  to
  specify:

          1. The name of your placeholder (DEFINE PLACEHOLDER).

          2. The associated language (/LANGUAGE).

          3. The type of placeholder: terminal, nonterminal, or menu
             (/TYPE).

          4. The description that you want displayed when the placeholder
             is used in a menu or in the SHOW PLACEHOLDER command.

          5. The end of the placeholder definition (END DEFINE).

       Example:
                     .
                     .
             DEFINE PLACEHOLDER subject_line -
               /LANGUAGE = MEMO -
               /TYPE = TERMINAL -
               "Subject of the memo."
             END DEFINE

  To define a token you use the DEFINE TOKEN command to specify:

          1. The name of your token (DEFINE TOKEN).

          2. The associated language (/LANGUAGE).

          3. The description that you want displayed when the token
             is used in a menu or in the SHOW TOKEN command.

          4. The end of the token definition (END DEFINE).

       Example:
                    .
                    .
             DEFINE TOKEN location -
               /LANGUAGE = MEMO -
               /DESCRIPTION = "Office location"
               "LOC:  URE-0096"
             END DEFINE
