FWIW I know this how most programs create CSV files. On the otherhand I
havent seen the poster respond to the effect that they are try to read in a
CSV file, only that they have a text string delimited by commas.
As for my Sig I wouldnt worry too much as we all have our own reality
whether we like it or not.
Normal People Worry Me!!!!!
I reject your reality and substitue my own!!!

FWIW, two delimiters stacked next to each other is exactly how most csv
creation programs would create a row that includes a field with a null
(missing) value. So this problem is pretty common. Basically, this guy is
trying to read a record from a csv file, and the safest approach is to
simply use the best SAS tool for the job (input statement with DSD and DLM
BTW Toby, your new sig file worries me. People who conceive of alternate
realities don't really strike me as the best types for programming work! I
hate it when a user swears up and down that in their "reality", they didn't
make some change to their system which produces some kind of malfunction.
When I finally track down the problem to what they actually did, their
"reality" most often gets a serious adjustment... ;-)
