I´m not acquainted with xlread(). I've seen that there is a function xls_read() though. In any case, one (advanced!) possibility would be to get the source code of the function, try to insert waitbar() in an appropriate place and use genlib to compile it back into a library. I'm not quite certain whether this would work or not, but I can't imagine another approach since I think Scilab is not capable of multitasking except when triggering an external process such as in playsnd(), which can play a sound file as a background process and go on performing subsequent commands. If the waitbar could be launched as an external process you'd be done as far as you can kill it at the end.

My issue is that I am calling a library function xlread that is very slow as it needs to load a large data set and I need to inform the user that something is happening.

The parallel run function does not seem to exist in the 2023.1.0 release , as I thought I may be able to use that instead. I am reading a large excel spreadsheet and it would be good to implement a progress bar . So, a periodic timer that runs in the background could be used to check a flag finish flag . If the finish flag is false increment the progress and fire the timer off again.
