I am trying to remotely connect to wrds libraries with sas. The code I'm using is: %let wrds = wrds-cloud.wharton.upenn.edu 4016; options comamid=TCP remote=WRDS; signon username=_prompt_; rsubmit; libname crspa '/wrds/crsp/sasdata/a_stock'; libname temp '/scratch/tau/noga'; libname link '/wrds/crsp/sasdata/a_ccm'; libname index '/wrds/crsp/sasdata/a_indexes'; libname cc '/wrds/crsp/sasdata/a_ccm'; I am able to sign in, however I recieve in the log the warning: One or more libraries specified in the concatenated library WRDSSEC do not exist. These libraries were removed from the concatenation. when I run the rest of the code: data compcrsp; set cc.CCMXPF_LINKTABLE; permno=lpermno; keep gvkey permno linkdt linkenddt; proc sort; by permno; run; I receive the following error message: error: libref cc is not assigned. the log is attached to this message. It is important to mention that I have run this program many times in the past, and there was no problem. I also checked the directories in wrds, and they have not changed. I don't understand why this error message appears now. please help me. thanks
