operation. The video mode is set to a text mode. The screen is cleared,
and the cursor is positioned at the upper-left corner of the screen.
1 = Transparent operation. If the video mode of
the outgoing foreground session is a text mode, no mode change occurs. The
screen is not cleared, and the cursor remains at its current position. If
the video mode is not text, or if this session has a VioSavRedrawWait
active, the pop-up is refused.
The OS/2 operating system is responsible for saving and restoring the physical
display buffer of the previous foreground session around a pop-up. This
is true whether transparent or nontransparent operation is selected.
