When I do wbak or rbak to a 6250 9-track tape drive, I often see error messages that say there was a bad tape block, or a read overflow, etc. I have a program that uses ios_$ system calls to open and read/write mag tapes. If tape errors happen during these calls, do I get the same error protection that happens in rbak/wbak? Or do I have to be double- checking to prevent errors? Also, a few OS updates ago, support for standard fortran/C io calls (OPEN or fopen of /dev/rmt8, etc) was dropped. I remember a lot of people were steamed about it, but I didn't care because I had nothing to do with it. Now that I do, has this support been reinstated, or do you still have to use IOS calls for program access to tape drives? Thanks, Scott Ferguson ferguson@erevax.bitnet Exxon Research & Engineering
