Library /sys$common/syshlp/patchhelp.hlb CHECK, NOT ECO  *Conan The Librarian (sorry for the slow response - running on an old VAX)

      Use CHECK NOT ECO to check  that  one  or  more  ECO  levels  are
      available for use in a particular image file.

      The CHECK NOT ECO command  is  the  negation  of  the  CHECK  ECO
      command.   It  too can be used to confirm that a particular patch
      has been applied to an image file.  Typically, however, the CHECK
      NOT  ECO  command  is  used  to  confirm  the ECO levels that are
      available for use in the current image file.

 Format:

      CHECK NOT ECO eco-level [:eco-level] [,...]

 Prompts:

 	ECO> eco-level
