[Info-vax] SOBGEQ vs SOBGTR

[Lawrence D'Oliveiro]

        ... set up loop count in Rn ...
        BR      9000$
1000$:
        ... body of loop ...
9000$:  SOBGEQ  Rn, 1000$

Why branch and use SOBGEQ instead of SOBGTR? So that, if the loop
count is initially zero, the branch falls right through without
executing the body of the loop.
