Even though it was published in 1993 you'll still find useful material in this Technical Report! Because of its emphasis on "batch-mode" reports and its chapter on calculating percentages, long-time PROC REPORT users consider P-258 to be a valuable supplement to the current documentation. However, finding a copy has been difficult even for insiders. Thanks to a group of hard-working folks in SAS Publishing who converted it to PDF, P-258 is now available via the web to all PROC REPORT users.
