There is no check whether there are enough data items on the stack available. The stack underflow happens only inside um/mod. The interpreter checks the stack only after the current word on the command line has finished. And here a um/mod with 2 cells as input leaves 1 cell, no underflow happens from the outside perspective. Is there a lint available for forth?
