Re: Vensim hangs when switching to Text view
A quick update, just in case anyone else encounters this problem. The issue appears to be caused by an 'ALLOCATE BY PRIORITY' function in the model and if I delete that equation the model returns to normal functionality.

Re: Vensim hangs when switching to Text view
I now have the opposite problem! I upgraded to the latest version of DSS 8.1 x64. Now, the model opens directly in Text view, but when I try to change to Sketch view, I get a STOP dialogue, saying 'Syntax error'. Following advice, I eliminated all the 'Supplementary' tags in the model, but that hasn...

Re: Vensim hangs when switching to Text view
Hello Tom,
I have emailed a copy of the model to vensim at vensim dot com.
I am using Vensim DSS 8.0.9 Double Precision (x64) on Windows 10

Vensim hangs when switching to Text view
Hello,
When I try to change from Sketch to Text view in a model, the Text view opens, but a pop-up dialogue box saying 'Formatting (model name)' appears and never goes away. I can't use Text view because of this, although I can return to Sketch view and continue working. Can I suppress this dialogue?

File copies
Hello,
I have been working on a sketch called eventman_experimental.mdl for several days. Now I find the directory is full of strange files, perhaps automatic backups, that I can't open. Can someone tell me what these files are?
Many thanks,
Phill

Re: Creating a constant value
I submitted that last comment before I had finished and I meant to add that this small model does use Euler integration.

Re: Creating a constant value
I'm sorry to be persistent, but this has piqued my interest now! I've added a 'Sample if true' variable and it works, but the value is augmented in the time steps subsequent to the calculation (the updated model is attached). I assume that this explanation in the help files is relevant, If you are u...

Re: Creating a constant value
I didn't explain that very well. The model has a javascript interface that will return 'additional item promotion budget' to zero after 1 time step, so it only carries the value of '100' for one time step.In this sketch view, you can see that the value of '20' was correctly calculated at TIME=5, but...

Creating a constant value
Hello, I need to calculate a value at a given point in time and pass that value as a constant for the rest of the simulation run. For example, in the attached simple model, FINAL TIME = 10. 'Additional item promotion budget' is a Gaming variable and If I enter $100 at TIME=5, the following variable,...

Re: Venapp editor problem
My operating system is Windows 10. It does seem to be linked to the latest release of Vensim, though, because my laptop runs exactly the same operating system but an older version of Vensim DSS and the problem doesn't happen on that machine.

Venapp editor problem
Hello, I'm using Vensim DSS 8.0.6 Double Percision x64. I have a VCD file template that I have been using for years and so was created in a much older version of Vensim DSS, but it has worked in all successive versions up to now. I use it because it has various parameters that I need. But now, when ...

DLL error
Hello, We run several models on a Unix server using the Vensim DLL and, up to now, we haven't had any serious problems, but we can't get our latest model to run at all. We're using Vensim(r) DLL(Multicontext/Silent) version 6.4d Double Precision running in Java. When we load the model file - it load...

'Find' command
I feel I am missing a simple trick here! I needed to change all the 'GET XLS' commands in a rather large Vensim model, so that the files Vensim fetches are 'xlsx', rather than 'xls'. So, I used the 'Edit' - 'Find' command the look for the relevant variables in Text view. But I can't find a 'Next' op...

Re: Publish model in VPM format from Vensim 8.04
It's a minor step to load a finished MDL to the older version of Vensim to publish the model as VPM instead of VPMX, so long as no 'backwards compatability' issues crop up. But we'd love to run both Vensim and Ventity models on a Unix server, so if ever you have the time to build Unix libraries for ...

Re: Publish model in VPM format from Vensim 8.04
I created the model in Vensim 8.04, then we found the published VPM file wouldn't run under the V7 DLL. So I loaded the MDL file from v8.04 into Vensim 7, published the VPM file from there and now it runs under the DLL on the server, without any problems.

Re: Publish model in VPM format from Vensim 8.04
Another question. Has the Vensim DLL changed too? I created an MDL in Vensim 8.04 and then we published that model as a VPM file in Vensim 7. We are trying to run it on our Unix server using the Vensim DLL, but the variable values are not changing as we run through the time steps. When we were only ...

Publish model in VPM format from Vensim 8.04
Hello,
I am running Vensim DSS 8.04 and models are published in VPMX format. A colleague with an older copy of Vensim cannot open these files. IS it possible to publish models in VPM format from Vensim 8.94? I can't see an option to do that and editing the file suffix doesn't work.
