Actually Raul, JOD dump scripts see: https://github.com/bakerjd99/joddumps
are very large J scripts that serialize code documentation databases. I've loaded dump scripts > 100 MBs without problems. Over the years I've hit various J system limits with these scripts that Roger and now Henry have either removed or expanded. I have a rule of thumb about software. Take the largest expected input and scale it by two orders of magnitude when concocting test cases. Good systems may not turn in awesome performance on such abuse arguments but they should not crash.
