RE: Verifying Existence of a File on a Server

I believe you are mistaken.

The user ID / password of the iSeries user running the command is
automatically passed when the QNTC file system is accessed.

Basically, to use QNTC at all you must have a Windows user ID and
password that matches the iSeries use ID and password.

Now this is very interesting.  If I understand the 
documentation correctly, the user doesn't necessarily have to 
have a valid i.d. and password on the Windows server.  I just 
have to pass "F_OK" as the second parameter (as in your example).

Do I understand correctly?  If so, that just leaves the setup of QNTC.

The iSeries can access Windows file shares via the /QNTC 
filesystem.  For 
example, we have a server named RED (that's just the name we 
used) and on 
that server we have a share named ISDOCS where we store our 
documentation 
for the Information Systems department.  If I wanted to access a file 
named "TimeMgt2.xls" in a folder called "scottk" I could 
refer to it from 
the iSeries using the following IFS path:

     /QNTC/SERVER4/isdocs/scottk/TimeMgt2.xls

When I use that path, it actually logs on to the Windows server named 
SERVER4 (using the userid/password of the iSeries user who 
tried to access 
it) and refers directly to that file.

If I wanted to check if that file existed, I could write an 
RPG program 
(or any other ILE HLL) to call the access() API.  That API 
checks whether 
a file exists (and optionally, whether you have access to it)  for 
example:

  /free
         filename = '/QNTC/SERVER4/isdocs/scottk/TimeMgt2.xls';

         if (access(%trimr(filename): F_OK) = 0);
            // hurray! file exists
         endif;
