|
|
|
<p>There are two mini-memory areas on the info panel. You can view memory in
|
|
|
|
|
|
Hex, (normal 7-Bit) ASCII, or Apple (8-Bit) TEXT format.</p>
|
|
|
|
|
|
<p>Control characters are shown in yellow. The Apple uses something called
|
|
|
|
|
|
8-Bit (High-Bit) ASCII, in which the first 128 characters (normal ASCII) are
|
|
|
|
|
|
also mapped onto the last 128 characters, but with a different
|
|
|
|
|
|
background. (Technically, the first 64 characters are drawn inverse, the
|
|
|
|
|
|
next 64 characters flashing, and the last 128 normally.) Some programs
|
|
|
|
|
|
will store text in this extended Apple format, where a High-Bit character can
|
|
|
|
|
|
be used as a flag to represent an end of word.</p>
|
|
|
|
|

<h3><a name="Memory_Search">Searching Memory</a></h3>
|
|
|
|
|
|
<p>You can search memory for hex values. Wildcard support is also supported
|
|
|
|
|
|
via the '<b>?</b>' wildcard operator, including nibble searching. A
|
|
|
|
|
|
single '<b>?</b>' by itself, means match one byte of any value. A hex
|
|
|
|
|
|
value with the high nibble or low nibble of '<b>?</b>' will mask off the
|
|
|
|
|
|
corresponding nibble. (At the moment there is no way to refer to the
|
|
|
|
|
|
list of results. A future version will support _# to reference
|
|
|
|
|
|
search result's addresses.)</p>
|
|
|
|
|
|
<p>Searching memory for text is forthcoming in a future version of the debugger.</p>
