@RUBY Not in LE

@RUBY[expression] : Returns the string result of the Ruby expression.  Note that the Ruby environment is persistent within a TCC tab window, so you can do things like:

       %@ruby[b = 42]

       %@ruby[p b]

which will print "42".  The value returned by @RUBY is the value returned by the RUBY API rb_eval_string.

You can query the type of the value returned by the last @RUBY call with the RUBYTYPE internal variable, and the value returned by the last @RUBY call with the RUBYVALUE internal variable.
