I've done some "prototyping" of algorithms in AmigaBasic, some fairly long. I've found it to be a good idea to periodically save your work; and (immediately after saving your work) periodically doing a SYSTEM to go back to Intuition. As time goes on, one can see that the available memory has shrunk and shrunk … most of it (though perhaps not all of it!) seems to be deallocated on return so one can then go back to AmigaBasic and reload the program, with a reasonable amount of memory and faster use once again. Failure to do this every so often will eventually crash the system, I assume by AmigaBASIC taking memory it doesn't have. Or is it an OS bug? I don't know. Very annoying whatever it is.
