  DCL Date Specifications? 
 The Question is:
 
I have a requirement of deleting files more than 7 days old. For this I am
 using /before option of the delete command. But how do I give the parameter
 (current day - 7 ) to the /before switch?
 
 
 The Answer is:
 
  DCL permits specifications of absolute, relative (also called delta)
  and combination dates.  Please see the help text -- please see HELP
  DCL DATE_TIME on V7.2-1 -- and please see the OpenVMS User's Guide
  for details on this.
 
  To delete all files older that 7 days, use: $DELETE/BEFORE="-7-"
 
  And when trying new DELETE command switch combinations, please practice
  using the switches on the DIRECTORY command first, to ensure that the
  command will select (only) the intended files.
