I know that in latex newcommand is defined as:

\newcommand{name}[num] {definition } 

But I want to define a new command which its argument is not defined between brackets and it is defined with between \begin and \end commands for example something like this:

\teststart bla-bla-bla \testend 

Maybe I should define two newcommand, one for \teststart and one for \testend.

I should mention that I have seen such commands in changebar package: \cbstart and \cbend.

Thanks
