Does this have a TOCTTOU hazard?

Why not use a standard facility such as BPXWDYN rather than RYO? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
