You can directly update the display of a PROGRESS control by assigning a value (which must be within the range defined by the RANGE attribute) to the control's PROP:progress property.

**Example:**

**BackgroundProcess  PROCEDURE        !Background processing batch process**

**Win  WINDOW('Batch Processing...'),AT(,,400,400),TIMER(1),MDI,CENTER**

**    PROGRESS,AT(100,140,200,20),USE(?ProgressBar),RANGE(0,200)**

**    BUTTON('Cancel'),AT(190,300,20,20),STD(STD:Close)**

**   END**

** CODE**

** OPEN(Win)**

** OPEN(File)**

** ?ProgressBar{PROP:rangehigh} = RECORDS(File)**

** SET(File)                  !Set up a batch process**

** ACCEPT**

**  CASE EVENT()**

**  OF EVENT:CloseWindow**

**   BREAK**

**  OF EVENT:Timer              !Process records when timer allows it**

**   ProgressVariable += 3         !Auto-updates 1st progress bar**

**   LOOP 3 TIMES**

**    NEXT(File)**

**    IF ERRORCODE() THEN BREAK.**

**    ?ProgressBar{PROP:progress} = ?ProgressBar{PROP:progress} + 1**

**                      !Manually update progress bar**

**    !Perform some batch processing code**
