Re: Use case with GET DIRECT LOOKUP
Thanks. The idea is to execute the math in the model using data from a given time period in that table (the csv file).

Re: Use case with GET DIRECT LOOKUP
My intention is to map steps in hours to historical data in years-days (time stamps, > 10000 lines in a csv file). I contacted a Vensim distributor who kindly tested this simple model for me and with a non PLE version. Before upgrading I’d like to be sure newer versions of Vensim can handle this sce...

Use case with GET DIRECT LOOKUP
Hi, I’m attaching a simple test model with GET DIRECT LOOKUP. I cannot figure out the kind of results in DataE. For example the table shows a value of 1 instead of 2 for steps 23 to 46.

Subscripts use case
I'm starting to develop a model representing growth of pasture for more than 30 paddocks in a farm with a rotational grazing scheme (1 paddock grazed -consumed- at a time). My first guess is that I'll need subscripts. But if I understand correctly, only up to 8 subscripts are supported by Vensim. Do...
