Hmm, this is contrary to examples I have seen. Is it new in the language? In the language references, for example in re !: section, it says to do this for execution time: 6!:2 y It doesn't say you need the single quotes. An I missing something or do the help pages need updating?
Thanks for your help. ___________________________ David Vaughan On 6 Jul 2011, at 13:29, Don Guinn <[email protected]> wrote: > Monadic ;: takes literal arguments.
