Dear colleagues!
I am developing a Data Checking syntax, in which I put the value 1 in
control variables if a corresponding condition is not kept. Then I select
the records, which have 1 in the corresponding control varible and issue a
list of the wrong records. When I do not have any records that have the
corresponding error, the selected records are 0. However, I do not know it
in advance and issue an empty list... I would be grateful if some of you
could tell me if it is possible to guess if I have selected 0 records in
order to avoid issuing an empty list in this case.
Thank you in advance!
With best wishes!
