Weird. After some RTFM in 'z/OS DFSMSdfp Advanced Services', I see this:

"The EXCP DCB does not have a field to contain the current or maximum block 
size but the DCBE does have such a field."

That field is DCBELEN, but nothing for DCB. Hmmm, I must also missing 
something...

Could you be kind to tell us why or for what purposes you want the length of 
that DCB? What device(s) or access method(s) are involved? Any reason why you 
need that length?
