Alternatively, submit PUT statements to create a temporary file. Each PUT statement is one line in the temporary input XML file. This code references the same filerefs as the previous code, and produces the same output.

data _null_;
   file myinput;
   put "<GetMetadataObjects";
   put "   <Reposid>$METAREPOSITORY</Reposid>";
   put "   <Type>Column</Type>";
   put "   <Objects/>";
   put "   <Ns>SAS</Ns>";
   put "   <Flags>1</Flags>";
   put "   <Options/>";
   put "</GetMetadataObjects>";
run;
proc metadata
     in=myinput
     out=myoutput;
run;
