Here is an example of one way to do this. I admit it is a little crazy, but it should show you some JCL that will give you an idea of what you can do. I have done the calculation in a new column in the data table you displayed in your first inquiry.

Here is the formula I developed for the new column
theList = {};
Insert Into( theList, :Nozzle 1 );
Insert Into( theList, :Nozzle 2 );
Insert Into( theList, :Nozzle 3 );
Insert Into( theList, :Nozzle 4 );
Insert Into( theList, :Nozzle 5 );
Insert Into( theList, :Nozzle 6 );
theList = Sort Descending( theList );
theOutput = Char( theList[1] );
theOutput = theOutput || ", " || Char( theList[2] );
theOutput = theOutput || ", " || Char( theList[3] );
theOutput = theOutput || ", " || Char( theList[4] );
theOutput;
