I am currently compiling a list of known issues and bugs for a library refresh. Hopefully these will go into RunLib when Ingo finds the time. That said, if you know of a bug or a problem with RunLib and wish it to be fixed could you please note it in this thread. This would apply to anything you think is not right, even incorrect error messages. I've found several commands in the library that issue a completely wrong error code as compared to the editor.
An example would be QSORT and SSORT don't work on 060 based machines possibly 040 as well, I am unable to test that myself. Reason: Self modifying code.
