In SAS, arrays can be defined with implicit or explicit subscripting. Current documentation only covers the explicit version and the implicit version is only supported for backward compatibility. This can cause problems for those tasked with the maintenance of legacy code. One can also find examples of recent conference proceedings in which implicit array coding is used. This paper will cover the syntax and basic usage of the implicit array. Additionally, several common array tasks will be presented in both forms. Familiarity with basic DATA step programming and array processing will be assumed.
