The service program for this is QSYS/QP0LLIB1. This'd make it
available in
RPGLE, I think.

YES!! access() is the function you want - in the Unix-type APIs.

In C, here's a macro to do this:

#include <unistd.h>
#define exists(x) (access(x, F_OK) == 0)  /* x is full path to object */

This works on anything you can specify with a pathname.

BTW, F_OK = 0.

There's also a national language version, QlgAccess(), that uses a
pathname
structure that includes CCSID, pathname separator infor, etc.

Is there an easy way for a program to determine if a file or directory
exists in the IFS?

In the QSYS.LIB file system we have CHKOBJ. But in the IFS I can't find
any reference to a function that will give me an easy answer. There
seem
to be many APIs that use files and directories, but nothing that
returns
an easy answer of 'Yes/No' for 'Does object exist?'

Many thanks in advance
