发帖数: 944 | 1 data WORK.NEW;
set WORK.OLD;
Count+1;
run;
The variable Count is created using a sum statement. Which statement
regarding this variable is true?
A. It is assigned a value 0 when the data step begins execution.
B. It is assigned a value of missing when the data step begins
execution.
C. It is assigned a value 0 at compile time.
D. It is assigned a value of missing at compile time.
我在sas上弄了一个 raw data,用这个命令Run出来，是有结果的。不明白自己是哪个地
方弄错了。
这个Count是在work.old里面，然后Count=sum(a,b).a,b都是work.old里的。然后在
WORK.New里面，count=count+1，对吗？
谢谢。 |
