How do I make sleep in Dyalog APL?


How to implement an analogue of Sleep() function in Dyalog APL?

Task context:

I have a CSV file, and for each line where I call a function, the function makes a network request, and because of their frequency, the server blocks me - I need to pause between each line. But how to implement this pause?

I tried googling, didn't help.


Solution

  • Next time, try APLcart instead of Google…

    The answer is ⎕DL which takes a number of seconds as argument and sleeps for that time. See the documentation for details.
