Hi Frank,
The limitation is for the entire data set... Rule: Direct data sets whose records are to be identified by relative track address must be limited in size to no more than 65 536 tracks for the entire data set. The above and more details can be found here... http://publibz.boulder.ibm.com/epubs/pdf/dgt3d410.pdf I don't believe this limitation has changed in the past few years, but you might want to check the doc for whatever version of z/OS you're running.

Is this limitation per extent or entire file size. >From the z/VSE LISTSERV: I believe it is 65K tracks per extent with a maximum of 255 extents for BDAM, but I can't find any doc to verify that right now.
