Suppose you need to
create an array named States with 50 character columns.
By default, array columns
are created as numeric and with the length of each column as 8. For
character columns, you can specify a length other than 8 following
the dollar sign ($).
The following example
creates the States array with 50 character elements named State1-State50,
each with a length of 12.
array States[50] $12 State1-State50;
If you do not specify
a length, the default length of 8 is assigned to State1-State50.
array States[50] $ State1-State50;
