Looking at the Vensim help, it appears not.

You could bring the data in to the model as a lookup and that would allow getting data at any value of model time.

When you select XCommand, you should also be able to select the correct function to call.

Can you e-mail me the screen you are using? I should be able to work out what is going wrong.

Hello Robbert,

The best thing to do would be to break the structure up into more manageable parts. Using Vensim, you can construct your model over a number of views.

Just a quick addition to the reply.

If you copy the Vensim.ini file into the MODEL directory for Sable, it will be loaded automatically and have the correct fonts etc on the graph.

To answer question the font information is stored in Vensim.ini - you can copy that from your windows directory and then use the Venapp command SPECIAL>READINI|vensim.ini to load that information. That should make the graphs appear the same.

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.

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.

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.

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.

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).
