^MC — Map Clear
Plain English
Clears the label's internal bitmap buffer. When set to Y, the bitmap is cleared before each label — this is the normal behaviour. Set to N to overlay multiple formats.
When to use
When you need to overlay multiple label formats on top of each other without clearing between them.
