If the first two bytes of the block contains a two byte block length, then all you may need to do is declare the file as VBS (variable block spanned).
I'm really rusty in BAL, but I think if you use GET MOVE logic, you should see a complete record in your record area. That is, z/os will obtain the record fragments and put them together for you. That may also be so in GET LOCATE where the record is presented to your program in contiguous storage as if it had been wholly contained in a single block. Again, really, really rusty in BAL. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Ward, Mike S Sent: Tuesday, July 15, 2008 1:18 PM To: [email protected] Subject: Circular buffer Hello listers, I have a question on circular buffers. I have an application that reads data in blocks. The data data I read is in 32k blocks. Each record in the block starts with a length in the first 2 bytes. When I get to the end of the 32k block I many have a partial record that starts in the next block I read. A colleague suggested I use a circular buffer. He's not to sure what it means and neither do I. I think it means to use the same buffer but in a circular fashion. The program is in assembler and I'm trying very hard to cope with it. Do any of you have a sample that I may borrow on how to do this circular buffer? Any feedback is welcome.
