发帖数: 413 | 3 you can use two input statement. in the first input statement, read the
first and another column (may 20th?) in the row.
input @1 tmp1 $1. @20 tmp2 $1. ..........;
if both are empty, do nothing ( conclude this line is empty)
otherwise, use the second input statement to read the variables you want.
I haven't touch input statement for a while and not sure whether the syntax
is correct. but make sure let SAS hold the current row in the first input
statement.

of the INPUT statement
