)GROUP name(s)

Gathers functions and variables into a group. The first name given will be the name of a group, and the subsequent names are those of variables, functions and operators to be placed in the group. If only the group name is supplied, the effect is to disband that group.

Groups can be used with the commands )ERASE and )COPY to deal with a set of objects in a single operation. However, they are generally considered obsolete, because APLX support 'indirect' )ERASE and )COPY, where the list of names is contained in an APL variable.
