-- Dumps indicated number (Count) of bytes, starting at the address given
|

-- 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"
|
|

|

|
|
