Bitmap-Handle
This property identifies the bitmap handle to be used. To obtain a bitmap handle use the W$BITMAP library routine with the WBITMAP-LOAD op-code. If this value is omitted, the control uses the bitmap most recently loaded by W$BITMAP.
If this property points to an animated GIF, then the Bitmap control renders the animation.
Example - Define a bitmap control with a handle that is set in procedure division
