I had already tried bootstrapping -diagt- directly without a user-written program, see below.
-bootstrap- squawks like it does when used with -rclass- functions but it does not deliver for -diagt-.
Of course it may be my mistake, but where am I going wrong?
Thank you for your consideration.

(running diagt on estimation sample)
Warning: Since diagt is not an estimation command or does not set e(sample), bootstrap has no way to determine which observations are used in calculating the statistics and so assumes that all observations are used. This means no observations will be excluded from the resampling because of missing values or other reasons.
If the assumption is not true, press Break, save the data, and drop the observations that are to be excluded.
Be sure that the dataset in memory contains only the relevant data.
