Re: ASCII questions
Hi Steve,
I believe that if you designate the ASCII data as /FORMAT=delimited (a.k.a. the
"COLUMNS" alias), that numerical fields present in the file as "******" will be
interpreted as missing values automatically. (So, too, will any other non-parsable
numeric fields.) Of course, there will need to be some kind of delimiter
separating the "******" fields from their neighbors.

P.S. Regrets that I have not been able to supploy the detailed syntax -- am offline
at the moment.
