I am vague on this but I believe that only CLOSE (if opened system will close on ABEND - last decade or two) will write an EOF on DASD, SMS or no SMS.
SMS checks bits in the Format1 DSCB on OPEN INPUT and does not attempt a READ. Just gives nice friendly EOF on first READ attempt. Without SMS - don't even think about it. Worst possible case is if the first track(s) of the extent contain data left over from a previous run of the program that supplies your input. Garbage/error reports to customers instead of nice clean ABEND. ---------------------------------------------------------------------- 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
