My first test case would fail without the CLL

BSW=JMS I BSWIND
*0170
C7700,  7700
BSWIND, BSWI

*0200
        CLA CLL CML    /CLEAR AC AND SET LINK
        TAD C7700        / AC <- 7700
        BSW                  /AFTER THIS AC SHOULD BE 0077
        HLT                    /LOOK AT THE PRETTY LIGHTS

BSWI, .-.

I believe this returns 0037 instead of 0077 if the CLL is left out of the
code, but I believe you figured this out.

I've been trying to come up with a way to reorder this but without
success.  I am going to have Warren look at it as
he has a twisted mind and sometimes sees things I miss.
