The articles below were written by Hunter Goatley and Ed Heinrich for a series on OpenVMS privileged programming. The series was published in VAX Professional (which later became Digital Systems Journal) in 1993 and 1994.
Please note that I didn't spend a whole lot of time converting the text files to HTML, so they're not as pretty as they could be. Also note that these versions differ slightly from the published, edited articles.
If you have any questions or comments, please direct them to Hunter Goatley.
