Library /sys$common/syshlp/dbg$help.hlb DEBUG, SYMBOLIZE, Examples  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    1.DBG> SYMBOLIZE %R5
      address PROG\%R5:
          PROG\X
      DBG>

      This example shows that the local variable X in routine PROG is
      located in register R5.

    2.DBG> SYMBOLIZE %HEX 27C9E3
      address 0027C9E3:
          MOD5\X
      DBG>

      This command directs the debugger to treat the integer literal
      27C9E3 as a hexadecimal value and convert that address to a
      symbolic representation, if possible. The address converts to
      the symbol X in module MOD5.
