  Re: Events in Robolab
 
Thanks for the response. I've been to that web site before and looked through it for event-driven programming.

Don't know specifically about Robolab, but usage might be.

  Re: Maximum Subroutine numbers?
 
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. (...) (22 years ago, 28-Dec-03, to lugnet.robotics.rcx.robolab)
 
  Is there a bug database?
 
Is there a bug database for Robolab? Unless it's the first perfect program ever written, there have to be bugs. Is there a procedure in place to report suspected bugs? Are they being cataloged, hopefully in a searchable database? (22 years ago, 28-Dec-03, to lugnet.robotics.rcx.robolab)
 
  Events in Robolab
 
After dozens of hours of experimentation, it is my conclusion that event-driven programming in Robolab is unreliable. Eventually, the RCX stops responding to events. This does not always happen at the same point in a given program, nor is it (...) (22 years ago, 28-Dec-03, to lugnet.robotics.rcx.robolab)
