Hi Claus,
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....
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.
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.

Hi all
The "Invalid buffer." message becomes even weirder. It is not in the
list of error messages:
https://help.scilab.org/docs/6.0.0/en_US/error_table.html
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.

Hello Claus,
In Scilab, clear is deleterious. As a first hint, i would try
commenting it before rerunning the script.
Best regards

Hi there
I've started to use the prettify functions by Pierre Vuillemin. So
far so good in Scilab 5.5
Now I've started to look into Scilab 6 (not least because graphics
is much faster), but I get a weird error.
If I start Scilab, first time I execute the code, I get an "Invalid
buffer." message.
Second time I execute the code then I get a bad message:
--> exec('C:\Users\claus\Documents\Scilab54\z3mfit.sce', -1)
at line 93 of executed file
C:\Users\claus\Documents\Scilab54\z3mfit.sce
'labels_font_size' , 3,...
^^
Error: syntax error, unexpected "'", expecting "," or )
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 ???
The "line 93" is part of the default options in Prettify, where it
says labels_font_size. It looks like this:
default_options = struct('title_font_size' , 4,...
'labels_font_size' , 3,...
'thicks_font_size' , 2,...
'num_format' , '',...
'leg_font_size' , 3,...
'line_thickness' , 2,...
'xstring_font_size' , 2)
Can anyone spot, what is the problem?
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.
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.
Best regards,
Claus
