I would like to retrieve the path of a caslib and store it as a SAS macro variable. 

 

I have been able to use the table.caslibinfo and print the result:

 

proc cas;
table.caslibinfo result=sss/caslib="Mycaslib"  ;
describe sss;
print sss; 
run;

Would I would like to do is somehow parse the result so that I just end up with the path (physical datasource path of the caslib) and store that in a SAS macro variable.  

 

For comparision If this was a SAS library (MYLIB )I would do something like this:

%let my_mvar= %sysfunc(pathname(MYLIB));

Does anybody have any ideas?

 

thanks

need to use the saveresult statement to create a SAS dataset from the result . i.e.

 

  proc cas;
table.caslibinfo result=sss/caslib="MyCaslib"  ;
describe sss;
print sss; 
saveresult sss  dataout=work.xdata;
run;

proc sql;
    select path into:myvar
    from work.xdata;
quit;

%put myvar = &myvar;

A CAS library points to a Viya App server in-memory location so there is no such thing as a physical folder path.

 

Have look at how a CAS LIBNAME is defined: https://documentation.sas.com/?docsetId=casref&docsetTarget=p088ys3kvgve4en12e8ug6jkkjxy.htm&docsetV...

 

Edit: Ah, but now I see you are referring to the source path of the CASLIB which you can list with the CASLIB statement:

caslib MyCASLib list;

 

I'm thinking it may be possible to redirect this output then read it into macro variables. I don't have Viya to test this though.

thanks, yes its confusing coming to Viya from SAS as there are similarities but also differences. I want to do exactly what you describe and redirect the output but haven't been able to work out how .
