Details
Merge control is set only in the WHIP! data. If set, Merge Control state applies to the drawable that follows it. In otherwords, Merge Control is supported as a rendition attribute for drawables.
Only Extended ASCII is supported, there is no binary or extended binary support. Use Cases
Draw a few black lines. Then draw a light gray solid over them. If the state is "lines overwrite", then the light gray solid will obscure the black lines in a gray-scale plot. If the state is "lines merge," the black lines will be visible.
