Re: CMD script macOS problem
Yeah, I'm not getting Vensim to quit/close at the end of my script, so I think MENU>EXIT is not working.

Quick aside: Is there a way to comment a line in a CMD file? I tried # but that gave an error. I don't see any comments in the examples.

Re: CMD script macOS problem
Ah, that is definitely a different way at calling the script. I shouldn't use the "open -a..." command from Terminal. Just call the Vensim binary directly with "/Applications/VensimDSS.app/Contents/MacOS/VensimDSS". I got my first script to work now. Please update the documentati...

Re: impossible to switch back to the old gui a model built with the new guide
Also, a great way to put Vensim models on the web is SDEverywhere (sdeverywhere.org). An open source project that is used by several big models, including En-ROADS (www.En-ROADS.org).
SDE has been developed and used for approx 8 years. Tested and still under development.

@mallari - thanks. Since your computer is pretty recent, I would suggest upgrading your version of macOS. Many developers support the current version (now 14) and maybe the previous two (12, 13).

Re: Bug: Very precise time settings for model
I understand the admin's point of view, but I'll try to represent a new user's perspective. Vensim is a very complex and daunting tool. Decimals create a cognitive load (for anyone) and scare students (and sometimes modelers). If Vensim can help a user by only displaying complexity and precision whe...

Huh, I don't remember this level of precision in previous version of Vensim (e.g., v8).

Bug: Very precise time settings for model
I don't remember this before, but it seems you can't have integer values for a model's INITIAL TIME or FINAL TIME. Or, at least, the formatters for the Model Settings window don't let you. I've tried removing the extraneous zeros but they always come back. Several models, not just one. Vensim 10.1, ...

feat: Add keyboard shortcut for Save As
There should be a keyboard shortcut for "Save As..." in the File menu. On macOS, most document-based applications use cmd-shift-S for the shortcut, which currently isn't used by Vensim. I recommend this. I needed to save a copy of a model and did the expected keyboard shortcut and it didn'...

Re: Random number generator; any tips to replicate?
Restating what I stated above for clarity: If a modeler wanted every RANDOM-based function in a model to be independent of all of the others (not drawing from the same pool), then the functions should be called with different STREAM_IDS (https://www.vensim.com/documentation/stream_id.html).

Re: Random number generator; any tips to replicate?
Interesting, some of that makes sense given my understanding of how RANDOM is working in Vensim. * The generator, for a particular "Stream", should generate the same values in the same order. * if you create a new variable that calls RANDOM() and additional time, that will use another valu...

Re: Random number generator; any tips to replicate?
So if someone renames variables or reorders views (or whatever might cause the "everything else" equations to reorder), the results of the RANDOM() function would change? I read Tom's comment above that they would be more deterministic and always ordered the same. For instance, a model has...

Reflecting on this a bit more... Again I'm grateful for your reply. Prevented a lot of headaches, I'm sure. I'm wondering how hard it would be to decipher or lookup Vensim's equation sorting. I'm not 100%, but I think the only rules SDE would need are the RANDOM-related rules. It seems like SDE woul...

BUG? Control-<number> not select analysis tool
In prior versions of Vensim, there have been the keyboard shortcuts to select sketch tools or analysis tools. Sketch tools are 1,2,3,4,...q,w,e,... and analysis tools were control-1,2,3,4,...,q,w,e,... I can select sketch tools with shortcuts still (though less consistently than before) but I can't ...

Re: Random number generator; any tips to replicate?
I'm glad I asked this before starting the journey! The equation ordering, and hence the order of rand() calls, seems like the most troublesome issue. SDE unrolls the the model equations, but probably in a way that is different than Vensim's implementation –– if only because there wasn't consideratio...

I'm looking into adding the RANDOM suite of functions to SDEverywhere.org.

Okay – that makes sense since the XMILE spec has "vendor-specific tags". Stella will have tags and Vensim could have tags for Vensim-only features too. Hopefully those extra tags are handled gracefully when being read by other applications –– that is the real key I would think. Import what...
