Re: BUG: XMILE file crashes upon opening

Please do share. Someone posted recently about another XMILE with a function that was not in the specification (Vensim now knows about this though).

Re: BUG: Table windows open in random locations

The next release of Vensim will store the window position for the new table tool. I'm still looking at the position where it first appears.

Re: BUG: Table windows open in random locations

Are you using the new or old table tool? Using the new table tool, mine opens in the same place each time (but you are right, if you move it, the location is not remembered). The old table tool should cascade (each subsequent one appears a little to the right and down of the previous one). Also, is ...

Re: Graph help.

Right click on the graph tool, and you will find a setting titled "X-Divisions". Select the "As global" option, and now your graphs should be missing the lines.

Not at the moment. It looks like you've found a bug, I'll experiment to see if I can fix it as there should be a way of removing the lines.

Re: Graph help.

I'm not sure what you are asking for. The graph will show the results in the simulation, Vensim will not show a straight line if the results are not constant.

Re: Matlab and Vensim

The vensim_get_run_info function is internal to Vensim, it should not have made it into the vendll.h file.

You can email the Matlab code to vensim@vensim.com, I can then include the important parts with DSS so others can use it.

ok, if you edit the vendll.h file, comment out line 140 so that it changes from CFUNCTION int VEFCC vensim_get_run_info(char *strRunName, int nInfoWanted,char *strReceivingBuffer,int nMaxBufLen) ; to //CFUNCTION int VEFCC vensim_get_run_info(char *strRunName, int nInfoWanted,char *strReceivingBuffer...

Re: Change view from text view to skecth view

That looks fine to me. Do you have RANDOM PINK NOISE defined as a macro?

What parameter follows this one in your Vensim file? Maybe the syntax error is with the next variable.

Re: Conversion of Stella Models to Vensim and Free vensim models

Sorry for the delay (it was a national holiday yesterday here in the UK). The model contains some non-XMILE elements. To make it work, you will need to replace SAFEDIV with ZIDZ and INIT with INITIAL. The next release will have these defined as macros so you will not have to do anything. Once I make...

If the extension is xmile, you should be able to upload it now. If not, less us know the file extension and I'll add it.
