data.label.isgroup
Syntax
- b := data.label.isgroup(lp,s<,slot>)
Check if the group s is associated with the label and return
true
if a match is found in any slot. The check for s will only occur in slot, if provided.A group index or slot index may be used for the arguments s or slot, respectively. Indices operate more efficiently than strings*.
Returns: Arguments: lp - label pointer
s - the group name or index*
slot - the slot name or index*; the check occurs on all slots assigned to the ball if omitted
Note
*Use the
group.find
andgroup.find.slot
intrinsics to obtain group and slot indices, respectively, and for further information.Use of the group logic is described in Groups.
