Use the OF <variable-list-specification> construct.

allvcatx=catx(':',of v:);

<variable-list-specification> can be any of the constructs listed in the help (see index:[variable lists] or search for page:[SAS Variable Lists])

---------------------------------------------------- data _null_; var1='123'; vxyz='abc'; z='ijk'; result=catx(':',z,of v:); put result=;

a = 1; b = 'a'; c = 2; d = 'x'; path = catx('/',of a--d); put path=; run;
