Hi
I have tried both ,, and ;; and they do not work. Upon further investigation I found that && does the trick.
You are, however, not allowed to do certain actions together, for example, you cannot do anything with collections, like a ClearCollect AND something else. If you do, you'll get an error, which basically indicates what only certain actions can be chained together. Setting variables, refresing data sources, etc. seem to work fine with the && operator. I have not tried all other action combinations, so do not have a definitive list, so you'll have to try and see what works.
See this example that I use in one of my apps. It updates an image data source, puts the images in a collection and then sets the image variable.
If(currentImageID = LastImageID, Refresh(Images)); //do this if true
If(currentImageID = LastImageID,ClearCollect(colImages, Images)); //do this if true
If(currentImageID = LastImageID,
Set(currentImageID, First(colImages).ID) //do this if true
&& Set(LastImageID, Last(colImages).ID), //and this if true
Set(currentImageID,currentImageID+1)) //else if false
If I had not had the need to put the images in a collection, the statement would have looked like this:
If(currentImageID = LastImageID,
Refresh(Images) //do this if true
&& Set(currentImageID, First(colImages).ID) //and do this if true
&& Set(LastImageID, Last(colImages).ID), //and do this if true
Set(currentImageID,currentImageID+1)) //else do this if false
