Can somebody tell me how to Frame with a gray line, like in DragrayRgn? I looked through IM 1-5 and could not find anything, but you see this kind of framing in almost any drawing programs. ==Chaoping cy03@andrew.cmu.edu

Then, frame the new rectangle. -- Ray Spalding Georgia Institute of Technology, Atlanta Georgia, 30332 uucp: ...!{allegra,amd,hplabs,ut-ngp}!gatech!prism!cc100aa Internet: cc100aa@prism.gatech.edu
