I am working on an assembler routine to quickly locate any block in a very large sequential dataset. I am using the DCBE option on the DCB and have specified the BLOCKTOKENSIZE=LARGE parameter in the DCBE. This seems to be working because BSAM is accepting the TTTR large file format.
The problem I am having is that I cannot POINT to a track beyond 00CD1308 and successfully read that track (I get a 42 condition in the ECB). An interesting side note is that when I do a POINT at 00CD1308, I can successfully read sequentially through the rest of the file (I know I am reading good records by the time stamps in each record). The TTTR addresses returned by FIND commands after each READ appear to be wrapping, though, never exceeding 00B00008 (there are 8 blocks per track). It looks like it is not handling large addresses in either the POINT or FIND. I would appreciate it if anyone help me see what I might be doing wrong.
