Perkins, contributed to SAS' early programming. The first versions of SAS were named after the year in which they were released. In 1971, SAS 71 was published as a limited release. It was used only on IBM mainframes and had the main elements of SAS programming, such as the DATA step and the most common procedures in the PROC step. The following year a full version was released as SAS 72, which introduced the MERGE statement and added features for handling missing data or combining data sets. #How to download sas university edition visualization full version# In 1976, Barr, Goodnight, Sall, and Helwig removed the project from North Carolina State and incorporated it into SAS Institute, Inc. SAS was re-designed in SAS 76 with an open architecture that allowed for compilers and procedures. The INPUT and INFILE statements were improved so they could read most data formats used by IBM mainframes. Generating reports was also added through the PUT and FILE statements. The ability to analyze general linear models was also added as was the FORMAT procedure, which allowed developers to customize the appearance of data. In 1979, SAS 79 added support for the CMS operating system and introduced the DATASETS procedure.
