Another partial source which ignores that you are authorized. When you are authorized (especially key zero/system key/supervisor) the system calls have different behavior. subpools for example: https://www.ibm.com/docs/en/zos/2.1.0?topic=summary-storage-subpools 6. Subpools 0-127, 131, and 132 are the only valid subpools for unauthorized programs. A request by an unauthorized program for a subpool other than 0-127, 131, or 132 causes abnormal termination of the program. > As I said when get the I/O area from sp=0 I abend 800 rc 4 from sp=233 which > is fixed its okay https://www.ibm.com/docs/en/zos/2.1.0?topic=codes-800 800 Explanation During processing of an I/O request, execute channel program (EXCP) processing encountered an error. Most instances of the X'800' ABEND code have a reason code that explains the error. After the pages for a buffer were fixed, an LRA instruction for a page in the buffer got a nonzero condition code. This means that page is not valid. 04 A program issued SVC 114, the EXCPVR macro, but an error occurred during page-fix or page-unfix processing. A page-fix error can occur if the EXCP processor tries to fix pages that are not assigned to the caller's ASID. So you convinced BSAM to use some authorized path for the I/O and tried to use as buffers storage it couldn't use for I/O... Try BSAM without authorization first and don't include any extra options you haven't researched, especially ones requiring authorization. The default for QSAM is that the open routine gets the buffers and you don't deal with buffers, you just get records. The default for BSAM is that you supply the buffers. The buffers can come from: a. you request storage from the system via getmain or storage etc.. b. you have the access method buffer management routines get buffers which you then ask for buffers. SC23-6852-03 z-OS DFSMS Macro Instructions for Data Sets V2R2 2015 dgt3d510.pdf The BUILD macro is used to construct a buffer pool in an area provided by the problem program. The buffer pool can be used by more than one data set through separate data control blocks. For BDAM, BISAM, BPAM and BSAM your program can obtain individual buffers from the buffer pool using the GETBUF macro, and return them to the buffer pool using a FREEBUF macro. For QISAM and QSAM, OPEN obtains buffers from and CLOSE returns buffers to the buffer pool. See z/OS DFSMS Using Data Sets for an explanation of the interaction of the DCB, BUILD, and GETBUF macros in each access method, and the buffer size requirements. c. storage in your program (obviously not reentrant). I've never taken path (b), only (a) or (c). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
