@Colin Brough - all great questions!  I'll provide some thoughts and I am sure others will chime in as well.  One question that I have which may impact the answers is what your current source control approach is?  Are you using serverside source control hooks with Studio or some other approach?

• Take Atelier off the list and drop it from consideration... it is deprecated new work shouldn't be started with it
• VSCode is the path forward for InterSystems technologies; it used the Atelier REST APIs and therefore you can use it on Caché 2018.x (originally added in 2016.2 IIRC)
• You can typically use VSCode alongside Studio, depending on your answer to the above question about your source control approach.  If you are using no source control, or if you are using serverside source control, then Studio and VSCode can both be used against the instance in mixed mode (my team has been doing this for years)
• I can't speak to what you lose with VSCode but I believe that at this point the answer is either 'very little' or 'nothing' for all intents and purposes
• I can't speak to Studio Templates (hopefully someone else can weigh in)

Hope this is a good starting point.

It is the actual code as it will be executed, so "Do ##class...."

Great - good luck with the certification exam!!  

Have you looked at the preparation and topic details at https://www.intersystems.com/healthshare-health-connect-hl7-interface-specialist?  

Check out %Dictionary.CompiledClass:

https://docs.intersystems.com/irislatest/csp/documatic/%25CSP.Documatic....

This is probably a good starting point for what you are looking to do.  Also, other tables in the %Dictionary package may be useful to you as well.

if you import this class into IRIS you will then be able to run the methods.  Look up the docs for $system.OBJ.Load() .. you will load and compile the class and the. you can call the methods like this:

Do ##class(User.Ready.ConvertCSV).ConvertN()

(I assume you cut out the actual logic of the methods when you pastes it above as what you pasted is incomplete)

@Cryze Zhang - it looks like this was an issue in prior versions as well.  

Did you know you can report this directly to the InterSystems Documentation team?  Click on the blue "Feedback" button on the right side of the screen and it will give you a chance to tell Docs directly what is wrong with the page.  Here is the 2021.1 link you can use for your convenience:
https://docs.intersystems.com/irislatest/csp/documatic/%25CSP.Documatic....
 

Thank you for noticing this and bringing it to our attention!  Please confirm once you have reported the issue and it will get addressed.

You are most welcome!  There is a lot of power there at your disposal ... enjoy the discovery process!

@Alistair Hutchinson - probably best to contact TrakCare Support on this:

Halt or just 'H'

@prashanth ponugoti - a couple of things to look at:

1) When you open the first link in /csp/healthshare does it open for you after authenticating?

2) Is your /csp/test web application definition set to work in the same namespace as /csp/healthshare?

3) Is a copy of your person.csp file moved to the web application root that you defined for /csp/test?

Hope that helps get you started on finding a solution.

Note ... make sure you have downloaded the actual Community Edition kit (if you did not then it won't have a license embedded).  Go to evaluation.intersystems.com and select the option for Community Edition to make sure you have the right kit.

@A.R.N. H Hafeel  - are you specifically interested in Caché or are you looking for the latest and greatest and therefore interested in learning InterSystems IRIS?

In the \bin directory is the csystray.exe file.  Run that to get the cube running.  Alternatively, you can use the cube that you do see in your systray and select "Remote System Access" to get to Studio, SMP, etc of your second instance.

Is there a single development server which all developers connect to?  If you are not able to have a fully isolated development environment for each developer then you will end up getting frustrated trying to use client-side source control.

You might want to consider the new server-side Git source control hooks which were recently launched:

https://community.intersystems.com/post/git-shared-development-environments

This won't solve your issue of working while not on VPN, but it will allow multiple developers to work against the same instance without stepping on each others' toes.  

I know this is an old thread, but we do have a solution available now for this scenario which will work with Studio, Atelier or VSCode.  See https://community.intersystems.com/post/git-shared-development-environments

Absolutely!  You will need to write a method that contains the SQL and then execute the method from a Task.  As the linked docs suggest, write your own task by creating a class that extends %SYS.Task.Definition: https://docs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls?... 

@Nicola Sartore - what does your organization use for a source control strategy?  if you use server-side source control hooks and you are on at least Cache 2017.1 (or any version of IRIS) then you can mix and match Studio and VS Code as VSCode fully supports server side source control (as well as client side, but if you are a Studio shop then you don't have any client side source control in place)

2021 Update - there is now a solution available that fills this need: https://community.intersystems.com/post/git-shared-development-environments
