Using CALL VNAME The most obvious method of creating a "variable name" data set is to use the CALL VNAME routine.

BASE SAS, MACROS, ROUTINES, FUNCTIONS, SAS Data Integration Studio, SAS in Mainframes VNAME(var) returns the name of the given variable. VNAMEX(expression) (a file reference name) is a shorthand reference to an external file. Once you have associated a fileref with an external file, you can use it as a shorthand reference for that file in SAS programming statements (such as INFILE, FILE, and %INCLUDE) and in other commands and statements in SAS software that access external files. I second Chris J's answer.
