<h3><a name="Memory_View">Viewing Memory</a></h3>
|
||
<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>
|
||
<p>Here is a summary:</p>
|
||
<ul>
|
||
<li>
|
||
<p style="MARGIN-BOTTOM: 0in"><i>Normal ASCII (non-control characters) will show up in
|
||
cyan; High-Bit text in white.</i></p>
|
||
<li>
|
||
<p style="MARGIN-BOTTOM: 0in"><i>Apple TEXT (normal ASCII) will also display with an
|
||
inverse background; High-Bit with a normal background.</i></p>
|
||
</li>
|
||
</ul>

<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>
