Re: [Scilab-users] command longer than 4096

[Federico Miyara]

Vincent,

A question to be sure we understood the underlying problem.
How did you get this error message?
-  Using SciNotes (F5 shorcut for example)?
-  Using exec function?
-  Using copy/paste?

When testing the code I usually select a portion of code from SciNotes and use the 
contextual menu "Evaluate selection with echo".

However, I notice now that with F5 I don't experience the same problem...!

But I also notice that in other cases of commands longer than 4096 the problem 
doesn't show. When I use .. to continue on the next line, there is no problem. 
When the same data is included in a single very long line the problem arises.

I'm including at the end two examples. In the first one the data are ordered 
with frequent ..'s, in the second one I removed all the continuation marks with 
the consequence that it will not be accepted.

The expected behavior would be that there were no difference between the 
different ways of executing a command.

As final note, among the answers I received when I posted my quest, one 
included the proposal of a function which allows to read massive data as in my 
usage case from a block comment at the end of the file. This would be 
interesting also in order to alleviate the code.

Regards,

Federico Miyara

Christopher,

Yes, you understand correctly my case.

There is a reason that justifies my request: I often use my scripts as examples 
within a didactic context. They are exhaustively commented, for instance. I 
consider it preferable to have all the needed data in the same script since I 
cannot be sure that potential future users who find my script will also find 
the associated file with the data (sometimes one downloads a file for future 
use without checking whether we are downloading all the associated files).

Then they should also change the script according to the particular directory 
tree where they choose to place the data, which is an unnecessary distraction 
from the very point of the example.

I agree that it wouldn't be convenient nor practical to work in this way with 
very large data sets, but some 1000 data is not unusual.

Regards,

To be sure I understand well :

in your Scilab script, you have something like



foo = [3.14, 1.414 ; 1.732 ...



with the 700 numbers written inside your script?



Of course your request is legitimate but IMHO, this is really not the best 
practice.

I warmly recommend to have the 700 numbers in a separate file.
