Command Sequence

The table below shows the Print Model command sequence for selecting a current pattern and using it to fill a destination image. The commands for specifying transparency modes, logical operations, and patterns are discussed beginning on the following page. Foreground color is described in Chapter 3.

Select Transparency Modes	?*v#N (source) and/or ?*v#O (pattern)
Specify the Logical Operation	If a logical operation other than the default
	(TSo-252) is desired, specify the
