Specifically, the condition where no parameters (p1com# and p1ent#) are passed in... If %eof occurs, the "AND" in the above applies when WSPRMS=0, correct?

No. If %eof is true, then the condition is true and the loop is exited.

If %eof is false, then you check the rest:

wsprms>0 and (stuff)

When WSPRMS = 0, that condition is false, regardless of "stuff". So if
WSPRMS = 0, then the LEAVE is skipped over. So, it *might* be an
infinite loop if WSPRMS = 0.

Other conditions that all have to be met for it to be infinite:

1. ARCMA1 is not empty.
2. There is no other (reachable) LEAVE in the DO loop.
3. There is no other (reachable) read of ARCMA1 in the DO loop.
