Hi All, We are moving a large number of mainframe SAS programs to the UNIX environment. The mainframe data steps often do not have a "run;" statement at the end. Queries often do not have a "quit;" statement at the end. My question is: what standards are appropriate for adding Run;" and "Quit;" statements? Obviously we do not want to spend considerable time adding these statements when it is not necessary. Much of the work will be done using SAS Enterprise Guide, and we went to make sure the code runs efficiently and correctly.
