Hi all,

I used
RECFM=VB,LRECL=32756,BLKSIZE=32760
and it worked...

There were two problems which I could found

1. RECFM=VB,LRECL=32756,BLKSIZE=0
does not work, the system was not automatically setting it correctly...
It was throwing error - "Invalid Record Length"...

2. The C program was not somehow reading this file correctly
After correcting the code, it was reading the file, and now I am able to browse it...

THANKS A LOT EVERYONE...

AshuSharma,

RECFM=VB,LRECL=32756,BLKSIZE=32760

The above DCB parameters worked fine,because you have to add a value of 4,since the file record format is of VB type.The first four bytes of the VB file contains the length of the record,so the blksize should be a multiple of LRECL + 4bytes.If it is a FB type then giving the multiple of LRECL will do fine i.e 32756 * 1==>32756

CHEERS,
VJ
