       tokens because there are none.
     - The only way there can be no lookahead present (in yychar) is if
       this state is a consistent state with a default action.  Thus,
       detecting the absence of a lookahead is sufficient to determine
       that there is no unexpected or expected token to report.  In that
       case, just report a simple "syntax error".
     - Don't assume there isn't a lookahead just because this state is a
       consistent state with a default action.  There might have been a
       previous inconsistent state, consistent state with a non-default
       action, or user semantic action that manipulated yychar.
     - Of course, the expected token list depends on states to have
       correct lookahead information, and it depends on the parser not
       to perform extra reductions after fetching a lookahead from the
       scanner and before detecting a syntax error.  Thus, state merging
       (from LALR or IELR) and default reductions corrupt the expected
       token list.  However, the list is correct for canonical LR with
       one exception: it will still contain any token that will not be

Parse the string @var{try} and evaluate it as if it were an Octave\n\
program.\n\
\n\
If execution fails, evaluate the optional string @var{catch}.\n\
\n\
The string @var{try} is evaluated in the current context, so any results\n\
remain available after @code{eval} returns.\n\
\n\
The following example creates the variable @var{A} with the approximate\n\
value of 3.1416 in the current workspace.\n\
\n\
@example\n\
eval (\"A = acos(-1);\");\n\
@end example\n\
\n\
If an error occurs during the evaluation of @var{try} then the @var{catch}\n\
string is evaluated, as the following example shows:\n\
\n\
@example\n\
@group\n\
eval ('error (\"This is a bad example\");',\n\

Programming Note: if you are only using @code{eval} as an error-capturing\n\
mechanism, rather than for the execution of arbitrary code strings,\n\
Consider using try/catch blocks or unwind_protect/unwind_protect_cleanup\n\
blocks instead.  These techniques have higher performance and don't introduce\n\
the security considerations that the evaluation of arbitrary code does.\n\
