Understanding base sas

[srinidhi]

Hi,

Is there any difference between @ and @@.

thanks,

Srinidhi

Yes.  Where are you using it?  If its reading in a file then @ specifies what column to read from, @@ holds the pointer over to the next line.  You may want to read up on data infile statements in the manual to understand where and when these are to be used.

The documentation for the INPUT statement has a good description of both options.
