The length of City_country is
A 6
B 7
C 17
D 25
大案是D，不知道如何得到的？ | P****D

Understanding Concatenation of Variable Values
SAS enables you to combine character values into longer ones using an
operation known as concatenation. Concatenation combines character values by
placing them one after the other and assigning them to a variable. In SAS
programming, the concatenation operator is a pair of vertical bars (||). If
your keyboard does not have a solid vertical bar, use two broken vertical
bars (¦¦) or two exclamation points (!!). The length of the new
variable is the sum of the lengths of the pieces or number of characters
that is specified in a LENGTH statement for the new variable. | r******m

if you change the length( ) with lengthc

put a;

results will be 23. |
