data ;
infile "" delimiter='09'x missover;
informat variable $10.;
谢谢!再问一个问题,missover是什么意思?英语不好,读不懂:
MISSOVER
prevents an INPUT statement from reading a new input data record if it does not find values in the current input line for all the variables in the statement. (“如果一个观测里所有的变量全是缺失的,则该观测不导入”是不是这个意思?)When an INPUT statement reaches the end of the current input data record, variables without any values assigned are set to missing.
Tip: Use MISSOVER if the last field or fields might be missing and you want SAS to assign missing values to the corresponding variable.
