RE: Does member exist?

We just use the CHKOBJ cmd in CLP and the File API QUSRMBRD in RPGLE.

Subject: Does member exist?


Is the Open Stream File (QHFOPNSF) API the easiest/best way to determine if
a file member already exists?  I am thinking of passing this call the path 
of /qsys/cartage/archinrex.rec010124 (member name being 'REC' = YYMMDD of 
file) and telling it not to open it if it exists, and not to open it if it
doesn't exist.  Then looking at the error that will be returned to determine
if it exists or not.  If it already exists, I'll add an 'A' to the end so
it becomes REC010124A and try again, then 'B' etc...

The reason I'm doing it this way is because I want this done in RPG, not CL.

My other option, I know, is to do an OVRDBF to the libarary/file.member and
try to Open the file name.  I just thought an API might be better.
