Hello, Encryption is only possible when a redistribution kit has been purchased. The kit allows models to be encrypted before distribution to protect the code within them. There is no way of protecting the model if only using runtime versions of the DLL. One more small bit of info, you need to purch...

Lee Jones is currently at the conference, and is trying to get hold of them.

They shoudl also appear on the Vensim website very soon. I will post another reply when they are available.

Also, to get data from a column and not a row, the 'time row or col' part of the function chances. If you put in an "A" then Vensim knows you are looking for a column of data, if you put in a "1", Vensim will look for a row.

Hello, I moved the post here as it is a more appropriate place for it. I hope you do not mind. You need to look at the functions GET XLS DATA and GET XLS CONSTANTS. If you go to the index at the Vensim documentation website, http://www.vensim.com/documentation/vensim.htm Type in GET XLS and you will...

Hello and welcome to the forum. It is very simple to do what you want. Look at the DELAY FIXED function in the Vensim help system. You would have the equation Z = X + Y and X = DELAY FIXED ( Z , TIME STEP , 0 ) You might need to check the syntax, but it should do what you want. Z takes on the value ...

Hello Anand,

You need to run your simulation as a game. Details of this are in the Vensim help system.

Tony.

Sable only works with binary Vensim files. Open your model in Vensim and click
"File->Save as"
There is a box where you can select the file type, select Binary and your model will be saved as a .vmf file.

You should be able to open this in Sable now.

Hello,

I am not entirely sure what you mean by submodel.

Can you give a real example?

Tony.

Vensim DSS comes with the Vensim DLL, this can be called from any application that can load a DLL.

Hope this helps,

If I have a paramater that is, for example, "percentage of population fertile", it is dimensionless. You multiply this by the population to give you the "population that is fertile". So for me, all percentages in my models are dimensionless. I would not manipulate the units at al...

Does the legend disappear completly?

This is not an error. The legend position has been set as custom. In this case, it is fixed in position, as the graph size increases or legend size increases, some of it is drawn off the canvas.

Hope this helps,

Tony.

There should be no problems under windows 2000.

Can you send me an example (Tony@ventanasystems.co.uk)

Unfortunatly not. But I will add it to the list of things to do.

The background should always be the standard windows dialog colour (so if you change the windows system colours then this will match it).

Tony.

You can use something like the following

sum variable[sub] =
sum (
if then else ( sub < m
, var[sub!]
, 0 )
)

Thanks Bob,

It is something I have on my list of things to do, so keep a watch on the forum.

Tony.
