could be a load address (some C64 binaries look like this). So let's start
with that assumption.</p>
<p>Click on the first line of code at address $1000, and select
Actions &gt; Remove Analyzer Tags. The $20 got absorbed into a string. The
Actions &gt; Remove Analyzer Tags. This removes the tag that tells the
code analyzer to start scanning for instructions at that point. (By
default, a code start point is placed on the first byte of a new project.)
Note the $20 is now part of a string directive. The
string is making it hard to manipulate the next few bytes, so let's fix
that by selecting Edit &gt; Toggle Data Scan (Ctrl+D). This turns off
the feature that looks for strings and .FILL regions, so now each
uncategorized byte is on its own line.</p>

<p>You could select the first two lines and use Actions &gt; Edit Operand
to format them as a 16-bit little-endian hex value, but there's a shortcut:
select only the first line of code, then Actions &gt; Format As Word (Ctrl+W).
select the first line, then Actions &gt; Format As Word (Ctrl+W).
It automatically grabbed the following byte and combined them. Since we
believe $2000 is the load address for everything that follows, click on
the line with address $1002, select Actions &gt; Set Address, and
enter "2000". With that line still selected, use
Actions &gt; Tag Address As Code Start Point (Ctrl+H then Ctrl+C) to
identify it as code.</p>
<p>That looks better, but it's branching off the bottom of the screen
(unless you have a really tall screen or small fonts) because of all the
intervening data. Use Edit &gt; Toggle Data Scan to turn the
string-finder back on.</p>

<p>That looks better, but the branch destination is off the bottom of the
screen (unless you have a really tall screen or small fonts) because of
all the intervening data. Use Edit &gt; Toggle Data Scan to turn the

<p>There are four strings starting at address $2004, each of which is
followed by $00. These look like null-terminated strings, so let's make
