I normally don't use anything but dd:myfile
and do all the other thing at JCL level.
But there is one other thing which I find pretty nice:
it's also possible to fopen a file using
dd:myfile(member)
and have the ddname myfile assigned to a PDS library,
this way opening, say
userid.my.pds.library(member)
Of course this is pretty flexible, esspecially if you compute the
fopen filename string at runtime, for example
strcpy (filename, "dd:myfile(");
strcat (filename, membername);
strcat (filename, ")");
It is possible to specify all those dsname and membername parts
using lower chars; they are converted to upper chars by LE.
Kind regards

Well, that's certainly pretty clear and explicit. Thanks. But unless I am
losing my mind, that is not the behavior I am used to seeing.
It would also be nice if they put this all in one place. I have read Chapter 5, "Opening
Files," about ten times. That's where I would expect to find information on, well, opening
files -- not under "Performing OS I/O Operations."
I am going to play with this some more. As I say, I don't think my other programs see
this behavior. fopen("FOO.BAR", ... tries to open FOO.BAR, not MYUSER.FOO.BAR.
(Yes, we run RACF.)
