I have a COBOL program which flows through MVS storage areas to get the DSN, 
VOLSERs, etc. for any open DD. I am currently getting the LRECL and BLOCKSIZE 
from the JFCB area. I always get the LRECL. However, for LBI files (> 32k  
blocksize) I always get zero for the BLOCKSIZE. This doesn't surprise me 
because the field in the JFCB is only 2 bytes long. Does anyone know how I 
would go about getting the larger block size? Thanks!
