## Description

The **Progress SET PROGRESS** method modifies the value of the progress bar along with the information shown in the progress window. It is useful for updating a progress bar within a loop.

In `id`, you pass the unique ID of the progress bar, returned by the [Progress New](Progress%20New.md) method.

In `progress`, you pass the current value of the progress bar. You can pass a Real value (between 0 and 1) or -1 to specify an undefined progress bar (also known as a "Barber shop" bar under Mac OS).

In `message`, you pass additional text to display under the main title (Windows) or under the progress bar (Mac OS). This parameter is optional.

Pass True in `foreground`when you want to force the progress window to the foreground of the application.

### Example  

Updating of progress bar:  

```4d
 $P:=Progress New // we create a new bar  
  // Carry out processing in a loop  
 For($i;1;100)  
  // ... code of processing  
  // Update progress bar  
    $r:=$i/100  
    Progress SET PROGRESS($P;$r;"More info")  
 End for  
  // Deletion of bar once processing is over  
 PROGRESS QUIT($P)
```
