yukai08008 2013-3-16 17:11
a. The automatic variables _N_ and _ERROR_ are incremented by one. b. The DATA step stops execution. c. The descriptor portion of the data set is written .(compilation phase) d. The values of variables created in programming statements are re-set to missing in the program data vector. Answer: By default, at the end of the DATA step, the values in the program data vector are written to the data set as an observation , the value of the automatic variable _N_ is incremented by one, control returns to the top of the DATA step, and the values of variables created in programming statements are set to missing. The automatic variable _ERROR_ retains its value.
