alias() itself returns currently selected alias.

In this case I was using this construction to alter cursor created by
create cursor command as copy of actual table and then adding fields to it.

something like

select clients
local arrStru(1)
=afields(arrStru)
create cursor rClients from array arrStru
alter table alias() add column CustTot n(12,2)
alter table alias() add column lastPur D(8)
.

But unfortunately this construct does not work anymore in VFP9
