You can do this with Object.Attach().
Suppose there is a form with a button and two textareas:

PUBLIC SUB Button1_Click()

  DIM p1 AS Process
  DIM p2 AS Process

  EXEC ["ls", "/" ] FOR READ AS p1
  EXEC ["ls", "/usr/lib" ] FOR READ AS p2
  
  Object.Attach(p1, ME, "proc1")
  Object.Attach(p2, ME, "proc2")

END

PUBLIC SUB proc1_Read()
  
  DIM aline AS String
  LINE INPUT #LAST, aline
  aline = aline & "\n"
  TextArea1.Text = TextArea1.Text & aline
    
END

PUBLIC SUB proc2_Read()
  
  DIM aline AS String
  LINE INPUT #LAST, aline
  aline = aline & "\n"
  TextArea2.Text = TextArea2.Text & aline
  
END
