/*
Scanner for the DDS. This file works with gnu's flex scanner generator. It
returns either DATASET, INDEPENDENT, DEPENDENT, ARRAY, MAPS, LIST,
SEQUENCE, STRUCTURE, FUNCTION, GRID, BYTE, INT32, FLOAT64, STRING, URL, ID
or one of the single character tokens `{', `}', `;', `=' or `\n' as
integers. In the case of an ID, the scanner stores a pointer to the lexeme
in yylval (whose type is char *).
The scanner discards all comment text.
The scanner is not reentrant, but can share name spaces with other
scanners.
Note:
1) The `defines' file dds.tab.h is built using `bison -d'.
2) Define YY_DECL such that the scanner is called `ddslex'.
3) When bison builds the dds.tab.h file, it uses `dds' instead of `yy' for
variable name prefixes (e.g., yylval --> ddslval).
