Other times a utility converts an error message to what the author assumes is more familiar language, but others find it less precise. I lately ranted in MVS-OE about a vague filesystem error reported by cp(1). Looking at SYSLOG showed an ABEND SD37 trapped and obfuscated by cp. Probably the C RTL. Dammit! They could/should trap the message text and make that also available to the programmer's console. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
