The Question is: Is there an appropriate syntax in the VMS PRINT command to print only the last page of a report without knowing the number of the last page beforehand? The Answer is : PRINT does not currently offer a "/TAIL" qualifier. If this is a Postscript file, you can often locate the length of the file from the following common Postscript sequence: %%Pages: (atend) %%Pages: 16 and would thus know that the file is 16 pages of Postscript output. Alternatively, you could simply search for the string "%%Pages:" in the Postscript file. With a queue and an ASCII text file, you would typically need to create a temporary (intermediate) file: $ TYPE/TAIL file.ext /OUTPUT=sys$scratch:tempfile.tmp $ PRINT sys$scratch:tempfile.tmp /DELETE If you can have multiple activities in parallel, you will want to append the system time and/or process ID to the filename in order to prevent filename collisions that can result from duplicates. With a spooled device and an ASCII text file, you can also use the following DCL command: TYPE/TAIL/OUTPUT=device: LOGIN.COM
