Hi there,   I'm new at using SAS so maybe my problem is easy to solve. I'm trying to implement a jackknife approach in a GLM analysis. For this purpose, I used the jackknife macro https://support.sas.com/kb/24/982.html so that the code was (variables in the model are not real, just to make it easy to read):   %macro analyze (data=, out=); PROC GLM DATA= GLM; MODEL Y = X + Z; out=out(rename=(_type_=stat _name_=with)); %bystmt; RUN; %mend; %inc "C:\route to macro";    %jack(data=GLM,id=stat with)   When running the syntax, two errors appeared: WORK.JACKDIST.DATA does not exist and WORK.JACKACT.DATA does not exist.   Any help?   thanks in advance ...
