Rob,

My favorite question for interviewers who care about where the data comes
from is - give an example where some of the values come from the first data
set.  A good followup question is to ask for an example where all of the
values come from the first data set.  Finally - under what circumstances
will the code guarantee which data set the values come from when the same
variable occurs in both files?

Although the last question may be easy, it places the emphasis where it
belongs on writing good data stable programs.

OK, given #1 for the length, where do the values for Division come from?  In
my runs it is the second of two datasets.  This creates a potential "gotcha"
for truncating those values does it not?

Here is a question.


The data sets both contain a variable named Division. What happens to the
variable in the output data set when the two data sets are merged?

1 Division has the length of Division in the first data set in the MERGE
statement.
2 Division has the length of Division in the last data set in the MERGE
statement.
3 Division appears twice in the output data set.
4 The length of Division changes depending on which data set contributes a
given value.


Answer is 1.


cheers,


SVN.
