/* Now the multiline macros, defined with addmmac()... */

/*
  Kermit's scripting language is so much more powerful than C that it was
  about a thousand time easier to implement FOR, WHILE, IF, and SWITCH
  commands as internal Kermit macros.  This was done in 1996 for C-Kermit 6.0.

  The following definitions, down to #ifdef COMMENT, are from C-Kermit
  9.0.304 Dev.22, April 2017, where the command parser was changed to not
  evaluate macro arguments on the DO command line, but to defer evaluation
  until after the arguments had been separated and counted.  This change
  required subtle modifications to the internal macro templates.

  IMPORTANT: Internal macros must have names that start with '_', followed
  by three letters, e.g. _whi for WHILE.  The definitions below are just
  templates for some other code that constructs the actual menu to be
  executed by filling in the \%x variables.  The generated macros have names
  like _whil2, _whil3, etc, where the trailing number is the execution stack
  level.  The reason for the strict naming convention is so internal macros
  can be parsed differently than regular ones.  See
  ckuusr.c:isinternalmacro(), which determines the type of macro.

  Get next command from TAKE (command) file.

  Call with:
   s     Pointer to buffer to read into
   n     Length of buffer
   f     File descriptor of file to read from
   flag  0 == keep line terminator on and allow continuation
         1 == discard line terminator and don't allow continuation

  Call with flag == 0 to read a command from a TAKE file;
  Call with flag != 0 to read a line from a dialing or network directory.

  In both cases, trailing comments and/or trailing whitespace is/are stripped.
  If flag == 0, continued lines are combined into one line.  A continued line
  is one that ends in hypen, or any line in a "block", which starts with "{"
  at the end of a line and ends with a matching "}" at the beginning of a
  subsequent line; blocks may be nested.

  Returns:
   0 if a string was copied,
  -1 on EOF,
  -2 on malloc failure
  -3 if line is not properly terminated
  -4 if (possibly continued) line is too long.

    table - a 'struct mtab' table.

    n     - the number of elements in the table.

  The keyword table must be arranged in ascending alphabetical order, and

  Returns the table index, 0 or greater, if the name was found, or:

   -3 if nothing to look up (target was null),
