[PD] [text define] functionality for text in structs?

[José de Abreu]

Hello, this is my first e-mail on the list, and i don't understand the code
of pd or anything like that, but I have an idea. Plus, sorry for bad
english.

If it was possible to have an array of pointers, maintained by the user, we
could jump to some scalar in the list, say I have 1000 scalars, and an
array with pointers to 100th, 200th, 300th, or any combination. This would
improve the search.

Maybe this would be a list/array of pointers inside another scalar? What do
you think?

Using this design, the user itself can create his own structures with
pointers, creating trees,  graphs with the scalars themself.

It make sense?
