Re: Compressing data sets (was Re: [SAS-L]) #2 #4
It's not a big deal, but there is a difference between reading a file
directly and having another program as an intermediary, and someone
someday is going to get into trouble because they didn't take that into

Yes, there are probably as many ways as people willing to post a solution, but your original request did say "So if we generated 200 respondents we

Indeed, I've actually used PGP in the past to encrypt data using
external calls (via the X command) to PGP's command line utility with
the following macro:
/*Encrypt the CSV File Created in Previous Step*/
x "pgp -tea +force c:\HF\SASExtracts\Extract&todaydate..txt
%let email@example.com; /*The public key for PGP encryption*/
Then, SAS automatically FTP's the encrypted file.
It worked well and met NIST standards for encryption and transmission of
data at the time.

I don't know much about STAT, but why don't you try something like:
If you want less output use 40 instead of 30 after RANUNI(0).
Don't know, if that does what you need...

I think that some good graphing can say a whole lot, and does not get
into the potentially problematic area of doing statistical inference
without thinking hard about it - always a dangerous area. Graphs can
be helpful in getting your ideas together about next steps, and if
done ethically and precisely they can be great descriptive tools to
support your other analysis.
Now you mentioned that you have several variables. Do you have a
single target variable and the others potentially affect this one, or
are all of the variables of equal or unknown importance?

The suggestion you provided using %BQUOTE got rid of the WARNING messages,
but did have the desired result in naming the HTML files. The COMPRESS
function only removed spaces, not punctuation - and the 2nd and 3rd
parameters on the COMPRESS function became part of the HTML file name.
Ex. nh_St.Mary's,'','p'.html nh_AnneArundel,'','p'.html
Any additional suggestions are appreciated. Thanks.
