My ancient experience and fading recollection of this is that none of the access methods seemed to look at DS1LSTAR - except to handle DISP=MOD. Certainly, not all programs reacted in the same way, but I put that down to some programs doing their own checking of DS1LSTAR. One program that certainly did "honor" DS1LSTAR, whether due to choice of access method, or by checking it itself, was ISPF Browse. That was the cause of much confusion (who you gonna call when you suspect a data set contains spurious data?) ---------------------------------------------------------------------- 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
