a) for semivariance analysis, i) default active lag distance as % of maximum distance possible (global default changed from 80% to 50%, but this can now be specified by the user ); ii) the default number of lag intervals (global default changed from 10 to 15, but this too can now be specified by the user);
b) for simulations, i) default number of simulations (global default = 1000), ii) default random number seed change (global default = no), and the default use of multigrid simulation (global default = yes).
