The compiler doesn't clear the subfields individually.  It creates the
clear value for the whole DS at compile time and handles the whole DS
(or each element of the DS array) in one instruction, not subfield by
subfield.

The /free version of CLEAR didn't do this until the fix for APAR
SE14962.

V5R2M0   : SI13771
V5R3M0   : SI15216 

I don't think you could beat the compiler's CLEAR with a hand-coded
version.
