Haven't seen any IBM-DSECT which is longer then 4096 bytes (z/os R4 and R7) Or do you think about you own DSECT for working storage or static areas?
Perhaps you can substitude the instruction like COPY IEABRC does? Oh well haven't spend so much time to look at it. You may post this to the Assembler listserver.

Thomas, I'm using the Long Displacement Facility quite a bit in a piece of code I'm writing now. It's not so much that I need it for the CSECT, but for the DSECT. Overall, I'm pretty satisfied with it. There is however, one consideration that I'll point out. There is no way to tell (that I have figured out) IBM macros to expand and exploit this facility. Any operands to fields that are past 4096 bytes of your closest USING do not assemble properly. (Examples, OPEN, GET) So, for big sections, you still need to have a register available for addressing around these macros. Todd FYI: How to test for this facility: USING PSA,0 TM FLCEFACILITIESBYTE2,X'20' BNO NOT_INSTALLED LONG DISPLACEMENT FACILITY NOT INSTALLED DROP 0 ...
