The VAX/VMS Image File Patch Utility (PATCH) allows you to make changes
to an image file in the form of patches.  You can then run the new version
of the image without having to compile, assemble, or link the program source
files.

Use the HELP command to get additional information on the following
PATCH commands:

  ALIGN      CANCEL     CHECK      CREATE     DEFINE     DELETE
  DEPOSIT    EVALUATE   EXAMINE    EXIT       expressions
  HELP       INSERT     mode       REPLACE    SET        SHOW
  UPDATE     VERIFY

Format:

        HELP topic [subtopic...]

where topic specifies the name of the command for which you need
help, and subtopic identifies a particular qualifier, parameter,
or command keyword about which you want further information.
