<p>Hi Claus,<br>
<br>
You need to spot where the 'invalid buffer' message comes from.
Adding 'pause' statements throughout your script may help you (or
is there a debugging step by step tool? I don't know). Or you may
want to comment suspicious parts of your code until there is no
more error....<br>
<br>
Do you read data at some point? I would intuitively suspect such a
message to be related to some data input/data reading operation
but I may be mistaken.<br>
<br>
Besides, I've encountered a similar behaviour where Scilab 6 seems
to work during the first run of a script but then something goes
wrong and nothing works quite right anymore (like error messages
out of the place) until Scilab is restarted. At this point I find
this version quite unstable.<br>

<br>
The "Invalid buffer." message becomes even weirder. It is not in
the list of error messages:<br>
<a class="moz-txt-link-freetext"
href="https://help.scilab.org/docs/6.0.0/en_US/error_table.html"
moz-do-not-send="true">https://help.scilab.org/docs/6.0.0/en_US/error_table.html</a><br>
<br>
I guarantee it's not an error message I've made up myself. The
entire script does not contain the word "buffer" (or "buffer.")
anywhere.<br>

In Scilab, <tt>clear</tt> is deleterious. As a first hint, i
would try commenting it before rerunning the script.<br>

<p>Hi there</p>
<p>I've started to use the prettify functions by Pierre
Vuillemin. So far so good in Scilab 5.5</p>
<p>Now I've started to look into Scilab 6 (not least because
graphics is much faster), but I get a weird error.</p>
<p>If I start Scilab, first time I execute the code, I get an
"Invalid buffer." message.</p>
<p>Second time I execute the code then I get a bad message:</p>
<p><br>
</p>
<p>--> exec('C:\Users\claus\Documents\Scilab54\z3mfit.sce',
-1)<br>
at line 93 of executed file
C:\Users\claus\Documents\Scilab54\z3mfit.sce<br>
<br>
'labels_font_size' , 3,...<br>
^^<br>
Error: syntax error, unexpected "'", expecting "," or )<br>
</p>
<p><br>
</p>
<p>When I run my script, the first thing my code does - it
clears all variables, all graphics and clears console, so
it's not "old" stuff from previous run that is the problem.
Or ???</p>
<p>The "line 93" is part of the default options in Prettify,
where it says labels_font_size. It looks like this:</p>

<p>Can anyone spot, what is the problem?<br>
</p>
<p>P.S. This part of the code is in a section that is
controlled by an if-statement, and even if I make sure the
condition is false (so that the Prettify code is not
executed), Scilab still spits out this error. It's really
weird - and even weirder it doesn't get the error the first
time that the code is executed.<br>
</p>
<p>P.S. My entire code is ca. 915 lines long + requires input
data, so I prefer not to attach it to a post here in the
mailing list.</p>
<p>Best regards,</p>
<p>Claus<br>
