Thank you for you response!
The problem is that I would like to select different start symbols at
run-time.
For example to have a function
parse(start_symbol, string)
So that can I write unit tests like
ASSERT_PARSES_CORRECTLY(parse(EXPRESSION, "3+2=4"))
%start would set the start symbol once and for all for the generated parser.
But again thank you very much for your response.
Regards,
Panayiotis

In my parser I have several productions. The start production is
named "program". Further down I have a production named "expression"

"expression" as the start production. Is this possible? My parser is
a C++ parser.
Perhaps you might try %start (see the Bison manual) and ignore any
messages about unreachable states.
