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.
