      /CAPABILITIES=DIAGNOSTICS
      /CAPABILITIES=NODIAGNOSTICS

   Specifies whether the compiler can generate diagnostic files.

      /COMMENT=(specifier,...)

   Specifies the character sequences of comments in the language. The
   specifiers are as follows:

   o  ASSOCIATED_IDENTIFIER=keyword

      Indicates the preferred association of comments to identifier.
      You can specify one of the following values:

      -  NEXT-Indicates that comments should be associated with the
         next identifier,

      -  PREVIOUS-Indicates that comments should be associated with
         the preceding identifier

   o  BEGIN=list of quoted strings

      END=list of quoted strings

      Defines the character sequences that start and end bracketed
      comments. A bracketed comment begins and ends with explicit
      comment delimiters. (Note that the beginning and ending comment
      delimiters can be the same, but need not be.) The list provided
      with the specifiers BEGIN and END can be any of the following:

      -  A string that is the one open comment sequence for the
         language. You must enclose this in quotes.

      -  A parenthesized list of strings, each one of which can be
         an open comment sequence for the language. You must enclose
         each one in quotes.

      The list accompanying the BEGIN specifier must be consistent
      with the list acompanying the END specifier. If the BEGIN
      specifier lists a string, then the END specifier must also
      list a string.

      Bracketed comments are recognized by the formatting commands
      (see the ALIGN and FILL commands) and placeholder operations
      (see the ERASE PLACEHOLDER command and the /DUPLICATION
      qualifier of the DEFINE PLACEHOLDER command).

   o  TRAILING=list of quoted strings

      Defines the character sequence that introduces line-oriented
      comments. A line-oriented comment begins with a special
      character sequence (consisting of one or more characters)
      and ends at the end of the line. The list provided with the
      TRAILING specifier can be any of the following:

      -  A string that is the one-line comment sequence for the
         language.

      -  A list of strings enclosed in parentheses; each string can
         be a line-comment sequence for the language.

      Line comments are recognized by the formatting commands and
      placeholder operations, just as bracketed comments are.

   o  LINE=list of quoted strings

      Requires that the comment delimiter be the first character that
      is not blank on the line. The LINE specifier is particularly
      useful with block comments, such as the following:

               /*
               ** Here is the inside of a comment
               ** which has LINE="**" specified
               */

   o  FIXED=quoted string, column number

      Used for languages that require that a specific comment
      delimiter be placed in a specific column, such as FIXED=("*",1)
      for COBOL.

      /COMPILE_COMMAND=string

   Specifies the default command string for the COMPILE command. (See
   the explanation of the command-string parameter in the COMPILE
   command entry.)

      /EXPAND_CASE=AS_IS
      /EXPAND_CASE=LOWER
      /EXPAND_CASE=UPPER

   Specifies the case of the text of the inserted template. AS_IS
   specifies that the inserted template be expanded according to
   the case in the token or placeholder definition. LOWER and UPPER
   specify that the inserted template be expanded in lowercase or
   uppercase, respectively.

      /FILE_TYPES=(file-type[,...])

   Specifies a list of file types that are valid for the language
   being defined. The file types must be enclosed in quoted strings.
   When LSE reads a file into a buffer, it sets the language for that
   buffer automatically if it recognizes the file type. For example,
   a FORTRAN file type (.FOR) sets the language to FORTRAN. Note that
   the period character must be included with the file type.

      /FORTRAN=ANSI_FORMAT
      /FORTRAN=NOANSI_FORMAT

   Specifies special processing for ANSI FORTRAN. Note that some
   commands behave differently when you use the /FORTRAN qualifier.
   Specifying NOANSI_FORMAT causes LSE to insert templates in non-
   ANSI (tab) format.

      /HELP_LIBRARY=file-spec
      /NOHELP_LIBRARY

   Specifies the HELP library where you can find help text for
   placeholders and tokens defined in this language. LSE applies
   the default file specification SYS$HELP:HELPLIB.HLB. If you want
   to access some HELP library other than SYS$HELP, you must supply
   an explicit device name.

      /IDENTIFIER_CHARACTERS=string

   Specifies the characters that may appear in token and alias names
   in that language. This list of characters is used in various
   contexts for the /INDICATED qualifier.

   The list of identifier characters also determines what LSE
   considers to be a word. A word is a sequence of identifier
   characters, possibly followed by one or more blanks. All nonblank,
   nonidentifier characters are considered to be distinct words.

   If you do not specify the /IDENTIFIER_CHARACTERS qualifier, LSE
   supplies the following values by default:

     "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ%$_0123456789"

      /INITIAL_STRING=string

   Specifies the initial text that is to appear in a newly created
   buffer.

      /LEFT_MARGIN=n
      /LEFT_MARGIN=1 (D)
      /LEFT_MARGIN=CONTEXT_DEPENDENT

   Specifies the left margin setting that is to be associated with
   the language.

   If you specify CONTEXT_DEPENDENT as the column number, then LSE
   uses the indentation of the current line to determine the left
   margin when you use the /WRAP qualifier. When you use the FILL
   command, LSE uses the indentation of the first line of each
   selected paragraph to determine the left margin.

      /OVERVIEW_OPTIONS=(MINIMUM_LINES=m, TAB_RANGE=(t1,t2))

   Specifies both the minimum number of lines an overview line must
   hide and the range of acceptable tab increments.

   The specifiers are as follows:

   o  MINIMUM_LINES=m

      Specifies the minimum number of lines an overview line must
      hide. The default is 1. For example, if the value of the
      parameter on MINIMUM_LINES is 5, then a line hides other lines
      only if there are at least five lines to hide. This specifier
      helps the user to avoid having very small source-line groups,
      and thus to avoid many expansion levels.

   o  TAB_RANGE=(t1,t2)

      The TAB_RANGE specifier indicates the range of tab values for
      which the adjustment definitions are valid. The default is
      (4,8). The second value must be at least twice the first value;
      both values must be positive. For example, if the tab range
      is (4,8), then LSE assumes that the adjustment definitions
      will work for any DEFINE LANGUAGE/TAB_INCREMENT value from 4
      to 8 inclusive. If you specify a /TAB_INCREMENT value outside
      the tab range, then LSE recomputes indentation to make the
      adjustments work.

      For best performance, it is recommended that you avoid
      recomputation by choosing a range that covers reasonable
      values. The numbers specified for the DEFINE ADJUSTMENT/CURRENT
      and DEFINE ADJUSTMENT/SUBSEQUENT commands must work for any tab
      increment value in the tab range.

      /PLACEHOLDER_DELIMITERS=(delimiter-specification[,...])

   Specifies the starting and ending strings that delimit
   placeholders. Placeholders can specify single constructs or lists
   of constructs. The delimiters for each type of placeholder are
   specified as a pair of quoted strings separated by commas and
   enclosed in parentheses.

   The format of a delimiter specification is as follows:

   keyword=(starting-string,ending-string)

   Possible keywords are REQUIRED, REQUIRED_LIST, OPTIONAL, OPTIONAL_
   LIST, or PSEUDOCODE. If you do not use the PSEUDOCODE keyword, the
   default is NOPSEUDOCODE. The maximum length of these strings is
   seven characters.

   The following is an example of a complete set of placeholder
   delimiter specifications:

     /PLACEHOLDER_DELIMITERS = ( -
      REQUIRED =("{<",">}"), -
      REQUIRED_LIST=("{<",">}..."), -
      OPTIONAL =("[<",">]"), -
      OPTIONAL_LIST=("[<",">]..."), -
      PSEUDOCODE=("«" , "»"))

   If any of the five keywords are not specified with the
   /PLACEHOLDER_DELIMITERS qualifier, LSE applies the following
   defaults:

     /PLACEHOLDER_DELIMITERS = ( -
      REQUIRED =("{","}"), -
      REQUIRED_LIST=("{","}..."), -
      OPTIONAL =("[","]"), -
      OPTIONAL_LIST=("[","]..."), -
      NOPSEUDOCODE)

      /PUNCTUATION_CHARACTERS=string

   Specifies the characters that are considered punctuation marks,
   or delimiters, in the language. When a placeholder name and its
   enclosing brackets are deleted, preceding white space is also
   deleted if there are punctuation characters to delimit the program
   constructs.

      /QUOTED_ITEM=(QUOTES=string [,ESCAPES=string])
      /NOQUOTED_ITEM

   Describes the syntax of certain language elements, such as
   strings, that require special handling for proper text formatting.
   LSE uses the /QUOTED_ITEM qualifier to detect comments properly.
   LSE does not acknowledge comment strings that occur within quoted
   items, nor does LSE acknowledge quoted elements that occur within
   comments.

   The value of the /QUOTED_ITEM qualifier indicates the syntax of a
   quoted item. This value must be a keyword list. The keywords are
   as follows:

   o  QUOTES

      This keyword is required, and must have an explicit value.
      The value must be a quoted string denoting all of the quote
      characters in the language. LSE assumes that quoted items begin
      and end with the same character.

   o  ESCAPES

      This keyword is optional. If given, then the value is required
      and must be a quoted string containing the escape characters
      for quoted items. Some languages use escape characters to
      insert quoting characters into strings. For example, C uses
      the backslash (\)  as an escape character. If you omit this
      keyword, then LSE assumes that the language inserts quote
      characters into strings by doubling them.

      /RIGHT_MARGIN=n

   Specifies the right margin setting that is to be associated with
   the language. By default, the right margin is set at column 80.

      /TAB_INCREMENT=n

   Specifies that tab stops be set every n columns, beginning with
   column 1.

      /TOPIC_STRING=string

   Specifies a prefix string to be concatenated to the /TOPIC_
   STRING qualifier specified in a placeholder or token definition
   before LSE looks up the help text for that placeholder or token.
   (Typically, this is the name of the language in the HELP library.)

      /VERSION=string

   Specifies a string that represents the version number of the
   tokens and placeholders associated with this language. You use
   the SHOW LANGUAGE command to display this string.

      /WRAP
      /NOWRAP

   Specifies whether the ENTER SPACE command (bound to the space bar
   by default) should wrap text when there is too much to fit on the
   current line. The /NOWRAP qualifier disables such text wrapping.

language-name
   Specifies the name of the language whose characteristics are to be
   defined.
