To me this looks like incorrect code and the warning about excess initializers is valid. Your saudacao2 is not an array of structs but just a single struct variable. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100599&aid=2791782&group_id=599 |
