The linkage stack and the XSB structure now has the extended PSW. Looking at 2.5 WTO I don't see any qualifications about the location of control parameters other than in the primary address space, which would imply above the BAR is OK. However, there is a general restriction "A program running in AMODE 64 should not call a service with data, parameters, or parameter addresses that are higher than 2 gigabytes, unless the individual service description indicates that it is allowed." So I do not know. -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
