Hi:
I believe the answer to #1 is for you to just remove the PROC PRINT from your code node. The data set will still be created -- what you're seeing at the bottom of your HTML output (after PROC REG) are the results of the PROC PRINT step. If you don't want to see it, then just get rid of it, now that you know how the data set looks.
As for #2, I believe, as described here
http://support.sas.com/techsup/unotes/SN/006/006976.html
that you are getting that message because SAS/Access to PC File Formats may not be licensed on the server machine (where EG is executing the code). In this Tech Support Note, the workaround is to create a CSV file, which for your example from PROC REG, would look like this:
[pre]
proc export data=work.parmest
outfile='c:\temp\parmest.csv'
dbms=CSV
replace;
run;
[/pre]
Your site may have licensed SAS/Access for PC File Formats (PCFF) but it is possible that the SAS/Access package was not installed on your server or installed on the server where you need it. To find out whether this is the case, you should contact the people who configure and install SAS at your company. If SAS/Access for PCFF has not been licensed by your site, but you're interested in obtaining a license, you should contact your sales representative.
