From: Francis De Brabandere <francisdb@gmail.com> Numeric literals raise type-mismatch (error 13) on unparseable BSTR; variables, arithmetic, C-coercion, function returns and parameters use string-compare instead. Cases needing the var_cmp rework are marked todo_wine. --- dlls/vbscript/tests/lang.vbs | 115 +++++++++++++++++++++++++++++++++++ 1 file changed, 115 insertions(+) diff --git
