From: Adam Majewski on 5 Jul 2010 16:57 Hi, I try to make complex number : (defvar s) (setq s 600) (defvar pos) (setq pos #c(s 100)) and get error : ;Argument REALPART is not a REAL: S ; [Condition of type SIMPLE-TYPE-ERROR but when change last statment to : ( setq pos #c(600 100)) all is good. I do not know why . Adam
