<SNIP> It depends on a setting in IGDSMSxx. The new default in z/OS 1.8 is to allow large format sequential data sets to be used without changes to the DCBE macro. But that doesn't mean SAS can use them without changes. I think programs that use note/point don't work without changes. <SNIP> This only works for a Wanna-Be large (DSNTYPE=LARGE). If the D/S has more than 64K tracks on any volume, then it doesn't work -- If the first volume is that way, you will get an ABEND S213, if it is on a subsequent volume, then ABEND S737. And for NOTE/POINT, it depends. There are now two formats for basic and large: TTR0 or TTTR. So you must give POINT the same format that NOTE gives so you know where & what to add/subtract. The format depends on the presence of BLOCKTOKENSIZE=LARGE in the DCBE. EXCP can do all of this (after all, all the Access Methods boil down to SSCH). It depends on just how much code you want to write and how many issues you want to handle. [Majority of this is from a co-worker who battled through all of this to support these options in one of our products here.] Regards, Steve Thompson -- Opinions expressed herein are those of the poster (under influence of Ed).
