Richard,

I would probably try using the PATHNAME function to get the physical name of
the directory represented by the fileref, then concatenate the "member name"
part (info.txt) to the end of that (with an appropriate delimiter in between
if necessary) as the argument to FILEEXIST.

In windows suppose I have a file

c:\temp\myData\info.txt

containing some data such as

1 2 3

pds-style filenaming is [ <fileref> ( <filename> ) ], where filename should
exist in the folder fileref points to I can use pds-style naming to read
from info.txt

filename myData 'c:\temp\myData\';
data abc;
  infile myData(info.txt);
  input a b c;
run;

But the FileExist() and FileRef() functions do not like the pds-style naming

%put Exists: %sysfunc (FileExist (myData(info.txt)));
%put Exists: %sysfunc (FileRef (myData(info.txt)));
Exists: 0
Exists: 20004

Any suggestions on how to check existence of file when given pds-style
filename ?
