SAS @ Symbol
The @ symbol at the end of an input statement in the data step tells SAS that not to move to the next data card after reading the values for the variables in the current input statement.
If sets of input values are split accross lines, or if single data lines are used accross iterations of the data step, @@ should be used at the end of the input statement. 公卫百科
The @ symbol is also used during column input to specify the columns of the data card at which values for a variable are to be read.
