Following up my own post with more information:
I found in the Minnesota FIRST League's Software Training Manual the
statement: "Local subroutines are identified and called by number
(1-8)." This suggests that unlike containers and most other indexed
objects in Robolab, subroutines don't use a zero-based index. (Why
isn't this documented?!)
However, increasing all five subroutine numbers in my program did not
change the way it functioned (below). Robolab does not produce an
error message; the program just gets to an infinite loop where an
event is supposed to get it out of the loop; after that I don't think
a nuclear blast could get it out of the loop (just kidding; the Run
button on the RCX will stop the program).

| I don't use Robolab, but I can offer some insight into how the RCX firwmare operates with subroutines (and events) that may partially explain your problems. RCX firmware supports 8 (eight) subroutines per slot. Internally they are numbers 0 to 7. (...) (21 years ago, 28-Dec-03, to lugnet.robotics.rcx.robolab)
