I don't understand how this could humor you, but I'll let the PoP explain what
"setting the bits in 15" means;
BRANCH ON CONDITION
...
A mask of 15 would indicate a branch on any condition
(an unconditional branch). A mask of zero
would indicate that no branch is to occur (a nooperation).
But it remains a BCR instruction, opcode '07'. There is no such thing as BR
instruction, as there is no '07F' opcode, that's an opcode with its first
operand alongside it.

Jan

Humour me and tell us all what setting the 4 bits in 15 means here. I had
actually looked at the green card on my home office wall (no really) and
figured the BCR 15,14 part out.
