Qualifiers

/ALL
   Displays the current values of all symbols in the specified
   symbol table (/LOCAL or /GLOBAL). If you specify the /ALL
   qualifier and do not specify either the /LOCAL or the /GLOBAL
   qualifier, the SHOW SYMBOL command displays the contents of the
   local symbol table for the current command level.


/GLOBAL
   Searches only the global symbol table for the specified symbol
   name. If you specify both the /ALL and /GLOBAL qualifiers, all
   names in the global symbol table are displayed.


/LOCAL
   Searches only the local symbol table for the current command
   level for the specified symbol name. If you specify both the /ALL
   and /LOCAL qualifiers, all names in the local symbol table for
   the current command level are displayed.


/LOG
      /LOG (default)
      /NOLOG

   Controls whether the system generates an informational message if
   the symbol value has been truncated. The value is truncated if it
   exceeds 255 characters.
