+   --  by Addr. The coding of this routine in its current form assumes the case
+   --  of a byte addressable machine (and is therefore inapplicable to machines
+   --  like the AAMP, where the storage unit is not 8 bits). The output is one
+   --  or more lines in the following format, which is for the case of 32-bit
+   --  addresses (64-bit addresses are handled appropriately):
+   --
+   --    0234_3368: 66 67 68 . . .  73 74 75 "fghijklmnopqstuv"

+   --  If Prefix is set to Absolute_Address, the output is identical to the
+   --  above version, each line starting with the absolute address of the
+   --  first dumped storage element.
+   --
+   --  If Prefix is set to Offset, then instead each line starts with the
+   --  indication of the offset relative to Addr:
+   --
+   --    00: 66 67 68 . . .  73 74 75 "fghijklmnopqstuv"
+   --
+   --  Finally if Prefix is set to None, the prefix is suppressed altogether,
+   --  and only the memory contents are displayed:
