Re: st: New program - snpgrab

[Nick Cox <njcoxstata@gmail.com>]

I trust that is an explanation for people working in the field.
Perhaps what such people do is start with an empty dataset and then
read in data and -snpgrab- uses more or less predictable names for
different variables.

It's not good practice in general that programs should make too many
presumptions about what names are, or are not, in use.

I imagine your help file will clarify these matters.
