Due to MISSOVER option...for the first observation
num1=11
num2=12
num3=.
num4=.
There is no Run statment to execute..so
ans " d "
b
You do not need a RUN statement following the null statement (the semicolon after the data
lines). The DATALINES statement functions as a step boundary, so the DATA step is executed as soon as
SAS encounters it.
