Steve, I looked over the Assembly manual & highlighted a few spelling corrections in BLUE. ( Revised copy on FTP site). We have a slight incompatibility in our MS-WORD versions. I am using WORD-95 & it had a problem with the formatting in your document. Let me know what version you are using & if the spelling corrections I made in BLUE are visible in your version. -Dan 73, Dan Welch w6dfw@qsl.net
