The Data step in SAS(R) 6.12 is the recipient of 50+ new functions. These new functions are broken into the following groupings data set functions, external file functions, library and catalog functions, special functions, variable functions, and statistical functions. The objective of this ...
1:基于前面的描述增加 SAS creates the FIRST.variable and LAST.variable for each variable listed in the BY statement 2:清空变量的方式有不同,The values of the variables in the program data vector are set to missing each time SAS starts to read a new data set and when the BY group changes。
