stata batch mode: xxx.do was interrupted. Would you like the batch job to continue

[qing xuan]

I try to use batch mode in stata

D:\s18\StataMP-64.exe /b do "F:\OneDrive\N\1mpg.do"

But I often encounter this error:

"1mpg.do" was interrupted. Would you like the batch job to continue? yes or no?

It pops up a dialog box and asks me to choose yes or no. If I click yes, it will continue to execute until I get the desired result, but if I choose no, it will end. I want to know, why does this dialog box appear, and how can I set it to choose yes by default?

If the content of my do file is as follows:

Then this dialog box will not appear.

sysuse auto,clear
global Ys "mpg price"
forval i=1/300 {
   foreach Yi of global Ys{
      dis "i"
   }
}

If the content of my do file is as follows:

sysuse auto,clear
global Ys "mpg price"
forval i=1/300 {
    foreach Yi of global Ys{
        reg "Yi" trunk length turn displ gear forei
   }
}

Then this dialog box will appear.

Is there anything special about the most basic reg command?

It’s interrupted because it encounters an error. The error arises because you need to use single quotes to expand a macro (e.g. `Yi'). Using double quotes is used for literal strings, which is why your first block of code runs (though it gives you the wrong output).

The error arises because you need to use single quotes to expand a macro (e.g. `Yi').

Clarification: to expand a macro you do not use ordinary single quotes ('Yi'). To expand a local macro, the opening quote is `, not '. The closing quote is the ordinary single quote '. If you use ordinary single quotes ('Yi '), you will again get the error message.

Clyde is correct, I showed the correct quotes but have not clarified the left quote is the back-tick.

Thanks! I have corrected the typographical error. It appears that this behavior is a characteristic of the Windows operating system. Additionally, I am curious to inquire whether it is possible to pass parameters in batch mode for a `do` file to accept and utilize. Could you recommend comprehensive resources for understanding this aspect?
