If the data set is SMS managed (or is it sufficient that SMS be active?) and DSORG is given in the "DD DISP=NEW,DSORG=PS,..." allocation will initialize the data set; no need for IEBGENER.

Is it that if an EOF is written, DS1LSTAR points to the second sector; if uninitialized to the first? What happens if the program attempts to read the data set now opened for output? >-----Original Message----- >From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of >Paul Gilmartin >Sent: Tuesday, May 18, 2010 11:07 AM >> >Depending on SMS, whether DSORG can be determined, etc. -- gil ---------------------------------------------------------------------- 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
