Re: st: List of variables with all missing (.) values?

Maarten kindly pointed to my -ds3-.
-ds3- I consider to be superseded by my -findname- (unless you are
using Stata 7 or 8, in which case you cannot use -findname-).
-search findname- in an up-to-date Stata (download the fixed version,
not the previous one).
findname, all(missing(@))
is the equivalent syntax to Maarten's suggestion. In fact, this finds
string variables that are all missing as well.
findname, type(numeric) any(missing(@))
finds numeric variables that are all missing.
Also, there is a difference between all missing and all equal to
sysmiss . -- which may or may not be important in your case.
Also, -search nmissing- and -search dropmiss- for other programs in
this territory,
Nick
