If you consider this as a limitation, the answer is yes, I think so. But if
you only dealing with dummies you can use the gen()-option of the -tabulate-
command instead. For example the command
.. tab v1, gen(v1d)
produces dummies v1d1, v1d2, ... v1dk for the categorical variable v1. This
is faster than -xi- and allows more control over variable names.
.. quietly tab v1, gen(v1d)
supresses the output, if you don't want to see it. With
foreach var of varlist v1-v100 {
quietly tab `var', gen(`var'd)
}
you produce dummies for variable lists.
