* We also want a reentrant scanner, so we have to pass the
* handle for the reentrant scanner to the parser, and the
* parser has to pass it to the lexical analyzer.
*
* We use void * rather than yyscan_t because, at least with some
* versions of Flex and Bison, if you use yyscan_t in %parse-param and
* %lex-param, you have to include the ascend_lex_scanner.h before
* ascend.h to get yyscan_t declared, and you have to include ascend.h
* before ascend_lex_scanner.h to get YYSTYPE declared. Using void *
* breaks the cycle; the Flex documentation says yyscan_t is just a void *.

The changes since TAOS 7.X are:
1) White space is added before "(task".
2) Task has a name, indicated by a subsequent string surrounded by a
double-quote.
3) Address expressed in hex number has a preceeding "0x".
4) Hex numbers are in lower case.
5) There is a character display corresponding to hex data in each line.
