/SYMBOL

   Specifies an alternate system symbol table for SDA to use.

   Format:

     ANALYZE/SYSTEM/SYMBOL=system-symbol-table

   system-symbol-table

   The file specification of the SDA system symbol table required 
   by SDA to analyze a running system. The specified system-symbol-table 
   must contain those symbols required by SDA to find certain 
   locations in the executive image.

   On Alpha and I64 systems, if you do not specify the /SYMBOL qualifier,
   SDA uses SDA$READ_DIR:SYS$BASE_IMAGE.EXE to load system symbols
   into the SDA symbol table.  

   On VAX systems, if you do not specify the /SYMBOL qualifier, SDA 
   uses SYS$SYSTEM:SYS.STB by default.  

   When you specify the /SYMBOL qualifier, SDA assumes the default disk 
   and directory to be SYS$DISK and [default-dir]; that is, the disk 
   and directory specified in your last SET DEFAULT command.  If no 
   device and directory are given in the file name and the file is not 
   found in the current default directory, SDA attempts to open the file 
   SDA$READ_DIR:filename.type. If no type has been given in the file 
   name, SDA assumes .EXE. If you specify a file for this parameter that 
   is not a system symbol table, SDA halts with a fatal error.
