In macro mode FIT2D will not prompt the user as to where or not variance arrays should be created. By default they will not be created. If this is not suitable then their creation may be specified on the command line by using the -var or -variances option. (-VAR, -VARIANCES, +var, +variances, +VAR, and +VARIANCES are equivalent.)
(The DIMENSIONS command may be used within a macro as an alternative method of creating variance arrays.)
