Back in the days of the dinosaur, your were able to log onto TSO, and give the command SAS. That would bring up an interactive version of SAS. For that to work, your TSO profile (wherever that is stored these days) must define what the SAS command means. Once you get it to work, you'll have to see for yourself what the interface looks like today, I couldn't tell you. However, note that you can bypass much of the JCL without jumping through these hoops. You can replace DD statements with SAS statements such as LIBNAME and FILENAME (even in a batch program). That is sure to work, but might require a little more detail such as adding 'DISP=OLD' to the LIBNAME or FILENAME statement.
