Examples

   1.$ SHOW SYMBOL PURGE
       PURGE = "PURGE/KEEP=2"

     The SHOW SYMBOL command in this example displays the current
     value of the symbol name PURGE. The command interpreter first
     searches the local symbol table for the current command level,
     then local symbol tables for preceding command levels, and
     finally the global symbol table. The single equal sign (=)
     following PURGE means it is a local symbol.

   2.$ SHOW SYMBOL/GLOBAL/ALL
         $FACILITY == "%X00000000"
         $IDENT == "%X00000000"
         $RESTART == "FALSE"
         $SEVERITY == "1"
         $STATUS == "%X10000001"
         LOG == "@LOG"
         TIME == "SHOW TIME"

     The SHOW SYMBOL command in this example displays all the
     symbols defined in the global symbol table. Note that the
     symbols $FACILITY, $IDENT, $RESTART, $SEVERITY, and $STATUS,
     which are maintained by the system, are also displayed.

   3.$ SHOW SYMBOL/LOCAL TIME
     %DCL-W-UNDSYM, undefined symbol

     The SHOW SYMBOL command in this example searches only the local
     symbol table for the symbol TIME. The response indicates that
     TIME currently has no value.
