DO WHILE STATEMENT

               Syntax:
               DO while (condition);

                             SAS statement;
                             END;
               This  executes  while  condition  is  true.  This  means,  if  condition  is  true  then  executes  SAS  statement
               otherwise stop. But condition will be checked only at the beginning of the loop.

               5.6 ARRAYS

                    SAS ARRAY:

               A SAS array is a convenient way of temporarily identifying a group of variables for processing within a
               data step. Once the array has been defined the programmer is now able to perform the same tasks for a

               series of related variables, the array elements.
                       ArrayIs a group of similar types of variables.
                       Array is used to perform same task on multiple variables.
                       Array is temporary and used only in data step. (Temporary means it can not store data and is
                       present only for execution time).

               Syntax:
                              Numeric array ::ARRAY arrayname(n) v1 v2....vn;
                              Char array    :: ARRAY arrayname(n)$ v1 v2....vn;

               Note: Arrays name must be follow SAS naming rules.
