PRINT/PAGE of (only) last page?

» close window

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
