17.1 dump

At the most basic level, memory can be examined byte by byte. To do this, use the dump command.

This command has the following synopsis.

dump [:from offset] [:size offset] [:ios int] [:ruler bool]
     [:ascii bool] [:group_by int] [:cluster_by int]

All arguments are optional, which means the simplest use of the command is to simply type dump:

The first row is the ruler which serves as a heading for each subsequent row. On the left hand side is the offset of the io space under examination. The centre block displays the hexadecimal representation of each byte, and on the right hand side is their ascii representation. If a byte is not representable in ascii, then the byte will be displayed as a dot.

By default the dump command reads from the currently selected IO space. However, it is possible to specify an explicit IO space using the ios option:

(poke) var myfile = open ("/path/to/file")
(poke) dump :ios myfile
