[Jprogramming] Domain errors with j701

[David Vaughan]

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.
