Good point, Mark - I'd forgotten about that. I ran into that exact scenario. I guess the trauma of the hunt as to "why aren't the buffers above the line?" is being blocked by my subconscious. :-)
Charles - what Mark said. :-D Later, Ray -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Mark Sent: Tuesday August 02 2005 08:13 To: IBM-MAIN@BAMA.UA.EDU Subject: Re: Reference for DCB coexistence with RMODE 31 programs? I recently encountered a gotcha. While doing something similar to what you are doing, I dynamically changed the DCBEDCB field before open with the appropriate DCBE address. I thought that would do the trick for the DCBE. But as it turns out, the DCBE= parm on the DCB is pretty much required, even if you use a dummy address. The invocation of that parm will set a couple of bits in the DCB that are required for processing. Without them, the system seems to ignore your DCBE address, and allocate the buffers BTL, and of course fail to free them after you close the file. So if you intend to use a DCBE address in your DCB, the parm must be coded in the DCB even if you have to use a dummy address at assembly time. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
