I thought it either succeeds or causes an ABEND (which could be trapped). Are programmers accustomed to testing RC after OPEN.
It's a holdover from a batch/production mindset: data sets are to be allocated statically, and there's no recovery when one can't be accessed. But, yes, I agree; OPEN should provide notification, via a mechanism that programmers have come over decades to handle, when it does something underhanded. -- gil ---------------------------------------------------------------------- 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
