Re: st: Re: Accumulating variable names to exclude from a varlist

[daniel klein <klein.daniel.81@googlemail.com>]

Partho,

I would not use a loop to this. Instead try something like

loc varstolookfor <your variable list here>
unab allvars : *
loc varsindata : list allvars & varstolookfor

The local macro "varsindata" will hold all variable names in
"varstolookfor" that appear in the dataset. However, I do not see why
you want to sort different datasets by different variables. This
question is for you to answer of course.

Also see

h unab
h macro lists

Best

Dear colleagues,

[...] I want to do the following:

Check a list of variables to see which of them exist in the file being
processed, build up a list of the ones that do exist, and then sort
the data by the existing variables.
