Subject: Re: Sample program for JES dataset read?
Perhaps I am over-complicating it. (I am just thinking; have not written any
code yet.)
I think I can use BPXWDYN() for that matter.
I am assuming that I can come down to fopen("//DD:ddname");

The only slightly tricky thing is the dynamic allocation, that that is pretty
straight forward for the primary subsystem.
You can even use __svc99() in the C library and then fopen("//DD:ddname",
....)
