    Resume
In summary, while running a long calculation in a cell, you can use Evaluation > Interrupt Evaluation to open a dialog box that offers the option of starting a subsession. To close the subsession and resume the original calculation, you can exit the dialog using Return[] or specify a specific return value with Return[expr]. It may not be immediately clear how this relates to the Dialog[] function, but it can be a useful tool in managing calculations.

TL;DR Summary
Ending a subsession in Mathematica
While running a long calculation in a cell, you can do Evaluation > Interrupt Evaluation. A dialog box appears, offering the option of starting a subsession.

But it's not clear how to close the subsession and resume the original calculation. I couldn't find anything on the net.

From https://reference.wolfram.com/language/ref/Dialog.html:
  • You can exit a dialog using Return[].
  • If you exit with Return[expr], then expr is the value returned by the Dialog function. Otherwise, the value returned is the expression on the last output line in the dialog.

Nice !
I would never have made the connection. It doesn't seem obvious what a front end menu UI dialog box has to do with the Dialog[ ] thing.
 

FAQ: How to close a subsession and resume the main session?

1. What is the purpose of closing a subsession and resuming the main session?

Closing a subsession and resuming the main session allows for a break in the data collection or experiment, while still maintaining a continuous flow of data. This allows for more accurate and organized analysis of the results.

2. How do you know when to close a subsession and resume the main session?

The decision to close a subsession and resume the main session is typically based on predetermined criteria. This can include reaching a specific time point, collecting a certain amount of data, or achieving a certain result.

3. What is the proper procedure for closing a subsession and resuming the main session?

The proper procedure for closing a subsession and resuming the main session will vary depending on the specific experiment or data collection process. However, in general, it is important to ensure that all data is saved and recorded accurately before closing the subsession and transitioning back to the main session.

4. What are the potential consequences of not properly closing a subsession and resuming the main session?

If a subsession is not properly closed and the main session is not resumed correctly, it can result in lost or inaccurate data. This can significantly impact the validity and reliability of the experiment or study results.

5. Are there any best practices for closing a subsession and resuming the main session?

Yes, there are several best practices that can help ensure the smooth and accurate transition from a subsession to the main session. These include clearly defining the criteria for closing a subsession, properly saving and recording all data, and thoroughly testing the process before beginning the experiment or study.
