1  SYS_LOADABLE
   There are several SYS_LOADABLE subcommands. Select the one you
   want from the choices below.
 

2  ADD
   Adds an entry in the system images file SYS$UPDATE:VMS$SYSTEM_
   IMAGES.IDX.

                                CAUTION

      The SYS_LOADABLE ADD command is not intended for general
      use. Only advanced system programmers should use this
      command.

   Format

     SYS_LOADABLE ADD  product image
 

3  Parameters
 

product

   A 1- to 8-character product mnemonic that uniquely identifies a
   loadable image. For user-written images, this should typically
   contain the string _LOCAL_.
 

image

   The file name of the system loadable image you want to add. A
   file name is the only value you can specify for this parameter.
   Do not specify a device, directory, file type, or wildcard
   characters.
 

3  Qualifiers
 

/LOAD_STEP

   Indicates the step of the booting process at which you want the
   image loaded. Valid load steps are INIT (which causes the system
   initialization code to load the image), and SYSINIT (which causes
   the SYSINIT process to load the image).

   If you do not specify a value for the /LOAD_STEP qualifier, it
   defaults to SYSINIT.
 

/LOG

      /LOG
      /NOLOG (default)

   Controls whether the SYS_LOADABLE ADD command displays a
   notification after the entry has been added.
 

/MESSAGE

   Enables you to specify the text of a message that is displayed
   when the appropriate condition is met (see the /SEVERITY
   qualifier). The default message is "system image load failed".
 

/SEVERITY

   Determines how the image load status will affect console output
   and booting progress. You can specify the following values for
   this qualifier:

   Value       Description

   FATAL       If an error occurs loading the image, display the
               error message and BUGCHECK information.
   INFORMATION Display the message and continue processing.
   SUCCESS     Continue even if loading the image produces an error.
               Does not display the message.
   WARNING     If an error occurs loading the image, display the
               error message and continue processing.

   If you do not specify a value for the /SEVERITY qualifier, it
   defaults to WARNING.
 

3  Description
   The SYS_LOADABLE ADD command adds an entry to the system images
   file SYS$UPDATE:VMS$SYSTEM_IMAGES.IDX. You can then process
   this file using the command procedure SYS$UPDATE:VMS$SYSTEM_
   IMAGES.COM. Processing the file with VMS$SYSTEM_IMAGES.COM
   generates a new system images data file that the system uses
   when it boots.

   If the file SYS$UPDATE:VMS$SYSTEM_IMAGES.IDX does not exist, the
   SYS_LOADABLE ADD command creates a new one.
 

2  REMOVE
   Removes an entry in the system images file SYS$UPDATE:VMS$SYSTEM_
   IMAGES.IDX.

                                CAUTION

      The SYS_LOADABLE REMOVE command is not intended for general
      use. Only advanced system programmers should use this
      command.

   Format

     SYS_LOADABLE REMOVE  product

                          image
 

3  Parameters
 

product

   A 1- to 8-character product mnemonic that uniquely identifies
   a loadable image. For user-written images this should typically
   contain the string _LOCAL_.
 

image

   The file name of the system loadable image you want to remove. A
   file name is the only value you can specify for this parameter.
   Do not specify a device, directory, file type, or wildcard
   characters.
 

3  Qualifier
 

/LOG

      /LOG
      /NOLOG (default)

   Controls whether the SYS_LOADABLE REMOVE command displays a
   notification after the entry has been removed.
 

3  Description
   The SYS_LOADABLE REMOVE command removes an entry from the
   system images file SYS$UPDATE:VMS$SYSTEM_IMAGES.IDX. You
   can then process this file using the command procedure
   SYS$UPDATE:VMS$SYSTEM_IMAGES.COM. Processing the file with
   VMS$SYSTEM_IMAGES.COM generates a new system images data file
   that the system uses when it boots.

   If the file SYS$UPDATE:VMS$SYSTEM_IMAGES.IDX does not exist, the
   SYS_LOADABLE REMOVE command creates a new, empty one.
