Re: download stel2ven.zip and/or stel2ven.exe
These are too old to be of any use these days. They are for converting models that are over 20 years old.

Re: writing text withe the Venapps tool
Sorry, I do not know what you are asking for help with.
Venapps are not very flexible, all you can really do is add textonly for each line of the paragraph.

Re: Sub-Subscripts?
You can define sub-ranges. For example
EUROPEAN COUNTRIES : ENGLAND, SCOTLAND, WALES, NORTHERN IRELAND, FRANCE
NON EURO COUNTRIES : USA, CANADA
COUNTRIES : EUROPEAN COUNTRIES, NON EURO COUNTRIES
Is this what you need to do?

Re: Percent
You haven't provided much information, so I'll guess.
Assuming you have a value that ranges between 0-1, create a new variable and plot that.
some variable = 0.5
some variable percent = 0.5 * 100

Re: Level initial series
You cannot set the initial population to be a time series, it's an initial value, so a constant. But I think the following will do what you need. population = INTEG(birth-death, initial population) population used before projections start = if then else ( time < 2023, historical pop, population).

No, you cannot export using PLE.

Re: Units conversion functions
Don't divide by 30 or multiply by 12. Vensim sees these as dimensionless numbers, so they will not change the units. If I see something like VALUE = some calculation / 30 My immediate question is "what does the 30 mean"? It's much better to create a constant, give it a name (average days p...

Re: Unit Errors
If that is correct, it probably should be something like
"Bull 12-18 Growing" = PULSE TRAIN(Avarage Herd First Calving Month, 0 , Calving interval , Productive LifeCyce )
And the units should be number/month.
"Bull 12-18 Growing" = PULSE TRAIN(Avarage Herd First Calving Month, 0 , Calving interval , Productive LifeCyce )
And the units should be number/month.

Re: Unit Errors
I think you have more problems here. Looking at "Bull", the equation should be simple. I'm not sure why you've got a PULSE TRAIN in there. bull = integ("Bull 12-18 Growing" - deaths bull - saled bull, INITIAL BULL) Then "deaths bull" should be measured in "number/m...

Re: Efficient variable declaration on subranges
All will work. Personally, I would use option 1, I find that way to be the clearest, one equation for each subrange. I don't like using :EXCEPT: statements as it makes it just a little more difficult to figure out what equation is responsible for calculating something, especially if there are multip...
