GROUP FIELD Syntax
Statement consists of a FIELD statement prefixed with the keyword GROUP.
The FP status response consists of a set of bit flags. The GROUP FIELD displays these flags as a batch; that is, it formats the whole byte as a hex number. (It could, by the way, use the Binary method instead of Hex and display them in binary notation.) The GROUP FIELD also creates a sub-tree in the Decode Pane. If the user expands the sub-tree then the items within the group are shown individually.
Here are two snapshots of the Decoder Pane, one showing the sub-tree closed and the other expanded:
