Software interface between SAS and the GDDM interactive chart utility.

Data from temporary or permanent SAS-data-sets on disk are transferred to the GDDM Interactive Chart Utility (ICU). Within the ICU these data can be displayed graphically, including all features of modification, supported by the ICU. The transfer is accomplished by a user written SAS procedure, which transforms the data from SAS internal format to the structure required to call the ICU from a PL/1 program. The interface provides interactive menu driven graphics from SAS-data-sets without the need to use SAS control language. The implementation refers to the CMS operating system.
