You need to use ',o rather than ,o; a port object can't appear unquoted in a Scheme form. Some implementations allow arbitrary unquoted data objects in forms, but that's an extension -- for example, in Chez you can write "(define foo ())" instead of "(define foo '())". -- John Cowan <[EMAIL PROTECTED]> http://www.ccil.org/~cowan But no living man am I! You look upon a woman. Eowyn I am, Eomund's daughter. You stand between me and my lord and kin. Begone, if you be not deathless. For living or dark undead, I will smite you if you touch him. _______________________________________________ Chicken-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/chicken-users
