My deepest thanks to Gene Gaunt, for his most excellent null map demo program, and to Sven, for sending the appropriate chapter of his e-book. While the demo works exactly as advertised, I've found that when I apply it to the actual application, there's an eleven-byte gap in the buffer between the end of the record and the beginning of the null map: i.e., where in the demo, the null map runs from byte 21 to byte 24 of the buffer, in the application, it runs from byte 32 to byte 35. Any idea what that 11-byte gap (filled with EBCDIC spaces, x'40') might be, and how to predict the size of it? -- James H. H.
