  Appending output to log using DCL? 
 The Question is:
 
I need to send the output of multiple commands to the same log file at
different times.  I am able to send the output to a log file by doing:
 
$define sys$output filename.log
 
However, the next time I use it, filename.log is overwritten, not appended.
 
Is there any way to append on the fly in this situation?
 
Thanks
 
 The Answer is:
 
  On OpenVMS V7.1, the following commands work quite nicely:
 
    $ PIPE SHOW USER | APPEND/NEW SYS$INPUT X.X
    $ PIPE SHOW SYSTEM | APPEND/NEW SYS$INPUT X.X
 
  Alternatively, a sequence such as the following can be used:
 
    $ OPEN/APPEND FOO X.X
    $ SHOW SYSTEM/OUTPUT=FOO
    $ SHOW LOGICAL SYS$TOPSYS/OUTPUT=FOO
    $ CLOSE FOO
