Re: [] (array access)

[Mike Cowlishaw-2]

There's no methods with those names, but nothing stops you writing your own
(with different names).  Or NetRexx will provide them if you declare your array
as an indirect property. For example (untested):

  class foo
     properties indirect
      bar=int[5]

See the NetRexx supplement for details.

I've read the supplement but that is not exactly what I thought of

        - it does only work with single indexed arrays
        - one has to use the getx... and set... methods


In Object Rexx I can use the '[]' and '[]=' methods in a way, that allows
me to use the objects very easy

(not tested)
a = .Matrix¨new
a[1,1]=2
say a[1,1]


class Matrix

::method '[]'
        expose theMatrix
        use arg a, b
        return theMatrix[a,b]

::method '[]='
        expose theMatrix
        use arg a, b, c
        theMatrix[a,b] = c

*****************

I could write a method in Netrexx, that takes 2 (3) variables, but I don't
think I could make the calls as easy as in Object Rexx.

Out of curiosity, why not inherit from netrexx.lang.Rexx. It already has these methods available for you....It may work (i've
not tested it....)
