Hi Statasticians

I have a simple problem, but wasn't able to find the solution:
I want to

a) find all variables whose names do NOT contain a given string (say, "tempsa")
b) have them stored in r(varlist)

Neither -describe-, -lookfor-, nor -ds- seem to be able to do the job. I've looked on the web and found Fred Wolfe's -lfsum-, which finds variables containing a given string with the possibility to exclude other strings. But this command is unable to handle wildcards, so that I cannot list ALL variables except for those containing the string "tempsa". (Also it does not store its results in r(varlist)).

I hope and assume that some of you will immediately know the solution since this must be a frequently encountered problem.

Best regards,
