As I recall, QSAM/BSAM can have a "logical record" >32K. But __only__ if it is VBS and __ONLY__ if you process each logical segment separately in your own code. That is, you cannot request that QSAM merge the segments together into a single logical record for you. The reason being that each segment contains its own LLBB field and the merged record also has a single LLBB field. The halfword LL field restricts the LRECL to <=32767 or it won't fit as a signed halfword.
Now, it think this means that COBOL itself cannot use LRECL>32K because I don't think COBOL supports separate VBS record segments being processed separately. But I'm not a COBOL programmer.
