_. Changed |
initial writing: 2008-02-14 |
The treatment of _. has changed; see dictionary page for details. Basically, primitives on arguments containing _. may not produce correct or consistent results, and primitives on arguments not containing _. signal NaN error instead of producing _. . A new verb 128!:5 is provided to test for _. .
