Hello, thank you for any insight or help you might be able to provide. I'm relatively new to SAS, and although I have some programming background, I am quite lost.    I created a new library using the "Add a new library" button and succesfully uploaded two data files. i dragged them into the library (called 'Thesis'), and tried running some simple procedures like 'PRINT'.    It gives me this error message: The SAS System was unable to open the macro library referenced by the SASMSTORE = libref SASUSER   It looks like I am not in the library 'Thesis' but in 'SASUSER', I can't figure if this is the problem and how to solve it. Can anyone point me in the right direction?    Thank you very much. I'm using SAS 9.3 ... View more
