Here is a shorter one for really storage constrained systems :-)

LOOPER  CSECT
LOOPER  RMODE  ANY
LOOPER  AMODE  31
        BR     15
        END

Well, here's a Q&D program that will just loop "for a long time":

LOOPER  CSECT ,
LOOPER  RMODE ANY        in case you're storage-constrained  :-)
        USING *,15
        STM   14,12,12(,3)       save caller's regs
          SR    2,2                zero outer loop counter
        SR    3,3                zero inner loop counter
LOOP    EQU   *
        BCT   3,LOOP             iterate inner
        BCT   2,LOOP             iterate outer
        LM    14,12,12(13)       restore caller's regs
        SR    15,15              set rc=0 
        BR    14                 return to caller
        END   LOOPER
