You can have multiple SYSMDUMPs. e.g. //SYSMDUMP DD DISP=SHR,DSN=SASDTP.SYSMDUMP,FREE=CLOSE //SYSMDUMP DD DISP=SHR,DSN=SASDTP.SYSMDUM2,FREE=CLOSE and if you just can't stand not getting _every_ dump, code a SYSUDUMP as the last one (without FREE=CLOSE): -- Don Poitras - zSeries R & D - SAS Institute Inc. - SAS Campus Drive mailto:sas...@sas.com (919)531-5637 Fax:677-4444 Cary, NC 27513 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
