Question(2)The following SAS program is submitted:
data WORK.TEMP;
length A B 3 X;
infile RAWDATA;
input A B X;
run;
########################################
Why is the above length of A is 3? rather than "Unknown"?
thank you!!! |

发帖数: 163 | 2 For the first question, SAS expects you to assign a length for X
For the second question, if you run the proc contents, you will see that the
length for variable A is 3. Even thought there is an error
in the lenght statement, that is only for X. And X is still have length of 8.
I hope this is clear. |

LENGTH A B 3 =LENGTH (A B) 3
SO BOTH A B ARE DEFINED 3
