Sergio,
?
It looks like only i was able to reproduce your problem, and understand what you were talking about.
I confirm that when PS dataset is created it is possible to use whole allocated space and add 698 lines of text to it,
but when PO(PDS) dataset is used, somehow there is lots of free space left, even more if number of members increased.
It is visible with hex editor, and i was looking for explanation everywhere. No one really knows why, and it is NOT documented.
As you have pointed out, with only one member it is the space for almost 31 full lines of text at the end of dataset - completely empty.
Did you find any information about cause of it?
?
Best wishes,
Andre
