b :=,s)

Remove the group s from zone gridpoint gp in all slots in which it is found.

A group pointer may be provided instead of a string. This is more efficient, which may be significant if this call is being made a large number of times. See the group.find function.


b - true if the group was removed from one or more slots of the gridpoint, false if the group was not found in the gridpoint


gp - a pointer to a zone gridpoint

s - the name of the group to remove
