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

      Use CHECK ECO to verify that the patches represented  by  one  or
      more  ECO  levels  have been applied to the image file.  Remember
      that an ECO  level  is  not  applied  until  the  patch  that  it
      represents  is terminated by the UPDATE command.  For example, if
      you  define  an  ECO  level  with  the  SET  ECO  command,   then
      immediately  check to see whether the ECO level is applied, PATCH
      returns an error message indicating that the  ECO  level  is  not
      applied.

      When you issue the CHECK ECO command, you do not have to list all
      the ECO levels that have been applied to a particular image file.
      However, specifying one or more ECO levels  that  have  not  been
      applied will produce an error message.

 Format:

      CHECK ECO eco-level [:eco-level] [,...]

 Prompts:

 	ECO> eco-level
