<p>I mean, the doc says that binary mode for writing or reading is
the default but it was not the case under Windows, where *text*
mode was the default, and in this mode char of hex code 1A is EOF
(in binary EOF is just a condition not a char).</p>

Thank you VERY MUCH!<br>

That works. Is there a fundamental reason why not specifying
binary fails somewhere? Some sort of EOF code that may
present itself randomly according to file content?<br>

Hello Frederico,<br>
<br>
On Windows, you should open your file in binary mode, with
"rb".<br>
--> fd = mopen("440Hz_0.2s.wav", "rb");<br>
--> h = mgeti(1000, "uc", fd);<br>
--> size(h)<br>
ans =<br>
1. 1000.<br>
<br>
--> dec2hex(h(1:5))<br>
ans =<br>
!52 49 46 46 84 !<br>

Dear all,<br>
<br>
I'm trying to read data from a file (in this case a wave
file) with the following code (Scilab 6.0.1)<br>
<pre style="font-family:Monospaced;font-style:normal;font-size:14.0;"><span style="color:rgb(0,0,0);">fid</span> <span style="color:rgb(92,92,92);">=</span> <span style="color:rgb(50,185,185);">mopen</span><span style="color:rgb(74,85,219);">(</span><span style="color:rgb(188,143,143);">'</span><span style="color:rgb(188,143,143);">g:\Mis documentos\Ondas\440Hz_0.2s.wav</span><span style="color:rgb(188,143,143);">'</span><span style="color:rgb(0,0,0);">,</span> <span style="color:rgb(188,143,143);">'</span><span style="color:rgb(188,143,143);">r</span><span style="color:rgb(188,143,143);">'</span><span style="color:rgb(74,85,219);">)</span>
<span style="color:rgb(50,185,185);">mseek</span><span style="color:rgb(74,85,219);">(</span><span style="color:rgb(188,143,143);">0</span><span style="color:rgb(0,0,0);">,</span> <span style="color:rgb(0,0,0);">fid</span><span style="color:rgb(74,85,219);">)</span>
<span style="color:rgb(0,0,0);">h</span> <span style="color:rgb(92,92,92);">=</span> <span style="color:rgb(0,0,0);">mgeti</span><span style="color:rgb(74,85,219);">(</span><span style="color:rgb(188,143,143);">1000</span><span style="color:rgb(0,0,0);">,</span><span style="color:rgb(188,143,143);">'</span><span style="color:rgb(188,143,143);">uc</span><span style="color:rgb(188,143,143);">'</span><span style="color:rgb(0,0,0);">,</span><span style="color:rgb(0,0,0);">fid</span><span style="color:rgb(74,85,219);">)</span></pre>
I should get a vector with 1000 unsigned 1 byte integer
components but I end with only 164 entries. Viewing the
file with an hex viewer, the last correctly read data are<br>
<br>
34 3E 34 3E <br>
<br>
(decimal 52 62 52 62)<br>
<br>
Then the following data and further data<br>
<br>
1A 3D 1A 3DÂ ...<br>
<br>
are not read at all. No warning like having reached EOF.
By the way, the repeated pairs are because it is a stereo
file with identical left and right channels.<br>
<br>
The same happens changing the way the file data are to be
decoded. Seems to get stuck when 1A or 1A 3D appears.<br>
<br>
Any idea of what may be going on and how to solve it?<br>
