Hi Pierre,
What you want to do is check your environment at context evaluation,
so simply write a "pause;" at the start of the context and when you
press Play
you will be prompted to resume in the Scilab console.
You can then write "-->who()" or "-->who('get')" to list all existing
variables.
Note that you can safely overwrite these variables because when you
leave your context the modifications will be lost (their scope is
limited to the context).

Paul

Hello Paul,
Thanks you for your quit response
It confirms that « tf » is a reserved word in Xcos context, and must
be used with caution.
In fact, I shall drive in September a student in Master2 on a subject
concerning turbines simulation, and I inherit a program done with Xcos
where condition « if ~exists(« foo ») foo=xx » is systematically
used, and I see a big number of Xcos blocks and hundreds of variables.
This is correctly done because all variables are not necessary
transmitted when launching Xcos. Part of them are redefined, part of
them are values by default, which explains this program structure done
by a student a few year ago.
So, has to control that, my main question was to know where I could
finf a list of reserved words or variables in xcos.
We have together seen that « tf » was one of them, which also define
the « Final Integration Time »
I had a look on the Help in Scilab (describing a lot of thing », very
clearly, but nothing about « tf » for example.
For example, what are the others reserved keyword for the rest of
these variables, in the above table ?
A list would be welcome, or a reference to access this one.
Your sincerely,
Pierre

OBJET : Re: [Scilab-users] Xcos - Problem with tf variable name in a
superblock
Hello Pierre,
100000 is indeed the "Final integration time" parameter in the
Simulation->Setup menu.
By using exists() (you might want to use isdef() [3] instead) you
don't override the existing parameters,
and in Scilab, functions can see the superior-scope variables (here,
'tf').
So just write "tmf=3; tf=2;" in your context and everything should run
fine.
Regards,
Paul

Hello
I retrieve an old xcos program about hydraulic simulation.
Worry :
A superblock containing a vairable « tf « doesn't match the value
programmed in the initialization part.
If « tf » a reserved word and where can I find a reserved list
Or is it a bugg ?
Are other variables concerned?
Thanks for yout help
Regards.
