I barely know what *I* have been paid to do, Mr Mattias, let alone 'consultants'... now, has your own drum ceased misbehaving or do you see further need to beat it? DD

It had just been so long since I had posted I felt obliged to contribute. Now if that contribution turns into a piece of shameless self-promotion, well... I guess it's not just the Irish who have luck, it's also the Polish kids from the South Side of Milwaukeee...... then again... http://www.friggatriskaidekaphobia.com/quotes.html MCM
From: Howard Brazee on 27 Dec 2006 10:44 Shops I was with used to use variable length files quite a bit until around a couple of decades ago - when they switched to files with header and detail records for variable data - which dominated for a decade or so until they switched to external databases for the same kind of data.
From: William M. Klein on 27 Dec 2006 18:29 Anyone interested in things related to "FS=39" in an IBM z/OS environment (with a currently supported compiler) may want to look at: "APPENDIX1.8 Appendix H. Preventing file status 39 for QSAM files" at http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IGY3MG31/APPENDIX1.8 As mentioned earlier, if you have (historically) used RECFM=U to handle some of these issues, you should also read: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IGY3MG31/3.5.4 -- Bill Klein wmklein <at> ix.netcom.com

It looks to me like RECFM=VB has to be a requisite (maybe RECFM=U, though I've not had any experience with that...). If it CAN be done with RECFM=FB, it'll be very interesting to see how... Thanks for your time. Pete. |
