Memory Dump
The memory dump allows any directly accessible memory (ie. memory which is directly
addressable and does not require access through a port) to be monitored. It is called from any
screen (except the PRINTER screen), by pressing the [F10] key and the [cursor left] key at the
same time.
The initial screen, (Figure 85) shows the data segment by default. Each screen shows the
segment (in hex) which is being viewed. In the left column is the starting address (in hex) for the
row of data. Eight bytes of data are shown in Hex, followed by the equivalent 8 ASCII characters
(if relevant). Additional data within the segment is viewed by pressing the [F8] and [F9] keys.
To change the segment and/or offset being viewed, press the [F7] key. A display similar to Figure
86 will be shown. Each successive press of the [F7] key toggles between highlighting the
segment and offset value. The highlighted value is the field which is currently being edited.
The segment:offset address is edited via the numeric keypad and the arrow keys. All values of
[0...9] can be entered directly via the numeric keypad. To enter a value of [A...F], the [cursor up]
and [cursor down] keys must be used to cycle through the possible values. Note that the value
[0...9] can also be entered via this method. Once a digit has been entered via the arrow keys, it
must be accepted by means of the [cursor right] key.
