ooRexx (Open Object Rexx)

Thanks for the recommendation. I will study it, but a little later, for now I am busy rewriting utilities that can work with a text window. If it is not too much trouble, I would like to receive a recommendation on this issue. In the future, I will need to develop the project into a simple analogue of a SCADA program. There will be a graphical window on which a schematic image of actuators (pumps, valves, etc.) will be displayed in accordance with their current state (work, downtime, failure, etc.)...

Yes, I think you should submit your refactoring as a patch.

Thank you Rick for reviewing the change, and for finding a nice (and more performant) way to extend it to cover other areas of code that could potentially be affected. Thank you also for your kind words. To be honest, with very little detailed understanding of the code, I adopted a narrow beam scattergun approach to add GC protections as well as sync code to any place in the code that I thought might be relevant to try and find something that would work. Eventually I got lucky but it took a while!...

Dom, the changes you described to the TraceObject code sound like a good idea as well, particularly moving the code in the NEW method into a proper INIT method. Other changes that might help would be to make any of the TraceObject class methods (including NEW) UNGUARDED, which will reduce the amount of old2new object tracking being done by the memory manager.
