Library /sys$common/syshlp/patchhelp.hlb SET, ECO  *Conan The Librarian (sorry for the slow response - running on an old VAX)

      Use SET ECO to define the ECO level for the ensuing patch.

      Whenever you apply a patch to an image file,  the  first  command
      you  type should be a SET ECO command.  This command provides you
      with a way to identify  your  patches  easily.   More  important,
      however,  it  lets  you  process selected patches using a command
      procedure.  When PATCH processes a command procedure, it searches
      the  file  for  ECO  levels  and  processes  only  those  patches
      represented by the specified ECO levels.  Patches not represented
      by ECO levels are not processed.

      You can issue as many SET ECO  commands  as  necessary  during  a
      PATCH  session;   however,  once  you  specify an ECO level, that
      level can never be used again for  that  particular  image  file.
      Furthermore,  whenever  you begin a patch with a SET ECO command,
      you must also terminate the patch with the  UPDATE  command.   If
      you  fail to issue the UPDATE command (1) the ECO level specified
      with the SET ECO command is not applied (hence, the patch is  not
      applied  to the image file), and (2) you cannot issue another SET
      ECO command.
