From: Francis De Brabandere <francisdb@gmail.com> When a block statement reaches EOF without its closing keyword, Windows returns a specific error code. Add error productions in the bison grammar for four unterminated block types: - If without End If (error 1014) - While without Wend (error 1018) - Do without Loop (error 1019) - For/For Each without Next (error 1020) Previously these all fell through to the generic E_FAIL path. --- dlls/vbscript/parser.y | 11 +++++++++++ dlls/vbscript/tests/run.c | 8 ++++---- 2 files changed, 15 insertions(+), 4 deletions(-) diff --git a/dlls/vbscript/parser.y b/dlls/vbscript/parser.y index c1a5b944268..f592139a68a 100644 --- a/dlls/vbscript/parser.y +++ b/dlls/vbscript/parser.y @@ -223,13 +223,18 @@ SimpleStatement | IfStatement { $$ = $1; } | tWHILE Expression StSep StatementsNl_opt tWEND { $$ = new_while_statement(ctx, @$, STAT_WHILE, $2, $4); CHECK_ERROR; } + | tWHILE Expression StSep StatementsNl_opt error + { ctx->hres = MAKE_VBSERROR(VBSE_EXPECTED_WEND); YYABORT; } | tDO DoType Expression StSep StatementsNl_opt tLOOP { $$ = new_while_statement(ctx, @$, $2 ?
