Using Arrays in SAS Programming

When an array is defined with the ARRAY statement SAS creates an array reference The array reference is in the following form: array-name{n} The value of n will be the element’s position within the array For example in the temperature array defined above the temperature for 1:00 PM is in the variable TEMP13

How do I use arrays in SAS?

Arrays simply provide an alternative method for referring to a variable rather than using the name of the variable. To use arrays in SAS code, first make sure that you understand the basic syntax of the SAS ARRAY statement. This section describes the ARRAY statement and provides a number of examples to illustrate its use.

How does SAS determine the number of variables in a weight array?

Notice the asterisk (*) inside the brackets in the WEIGHT array above. SAS must be able to determine the number of elements or variables in the array when it compiles the code. SAS determines this either by using the constant value that is specified in the brackets or by counting the number of variables in the variable list.

Can I put a variable name in a bracket in SAS?

Note: SAS must be able determine the number of elements or variables in the array when it compiles the code. Therefore, you cannot place a variable name in the brackets, as illustrated in the following statement, with the intent of SAS referencing the name to determine the number of elements:

Which SAS statement computes the value of a variable OK?

The SAS statement that computes the value of the variable OK needs a word of explanation. First, the logical comparison P EQ 0 returns a value of true or false, which is equivalent to a 1 or 0. This value is then assigned to the variable OK. Thus, the variable OK is set to 1 for all valid values of ANSWER and to 0 for any invalid values.
