If in the batch command, there is no need for delay at all. The result is relatively slow, but the next step偏偏 needs to use the result. The next step will not be reached until this step is not completed. If this step is completed, the next step also has the result available. DOS commands have only one pointer.
If other programs or files are called in the batch processing, start /w will do, and there is no problem of a new window.
I only know that choice is used to delay and then automatically input the value,
I really don't know how to apply this delay.
If you want multiple batch processes to run simultaneously, and the obtained results need to be used by each other, this kind of application should be wrong. Could this be multi-threading under DOS.
