/*
   Scanner for the DAS. This file works with gnu's flex scanner generator. It
   returns either ATTR, ID, VAL, TYPE or one of the single character tokens
   `{', `}', `;', `,' or `\n' as integers. In the case of an ID or VAL, the
   scanner stores a pointer to the lexeme in yylval (whose type is char *).

   The scanner discards all comment text.

   The scanner returns quoted strings as VALs. Any characters may appear in a
   quoted string except backslash (\) and quote("). To include these escape
   them with a backslash.
   
   The scanner is not reentrant, but can share name spaces with other
   scanners.
   
   Note:
   1) The `defines' file das.tab.h is built using `bison -d'.
   2) Define YY_DECL such that the scanner is called `daslex'.
   3) When bison builds the das.tab.h file, it uses `das' instead of `yy' for
   variable name prefixes (e.g., yylval --> daslval).
   4) The quote stuff is very complicated because we want backslash (\)
   escapes to work and because we want line counts to work too. In order to
   properly scan a quoted string two C functions are used: one to remove the
   escape characters from escape sequences and one to remove the trailing
   quote on the end of the string. 

   jhrg 7/12/94 

   NB: We don't remove the \'s or ending quotes any more -- that way the
   printed das can be re-parsed. 9/28/94.
