You can use this macro, which was in a recent issue of SAS Observations;
before calling the macro, you may need a libname statement to define the 
libref parameter (lib) and a filename statement to define the output 
fileref parameter (out). It worked ok for me but I didn't find it was 
perfect when it comes to character variables with quotes in them.
