[PD] Two ds questions

[Jonathan Wilkes]

1. Is "an instance of a data structure" synonymous with "scalar"?

2. append-help.pd says the first creation argument of [append] specifies the 
"template of a new scalar to append," but in 4.data.structures/01.scalars.pd, it says:
"Scalars are described by "templates", which are subwindows."  This is 
problematic because if you name the subwindow "foo" and the struct 
contained within "bar," [append foo x y] won't work.  Plus, many of the help 
patches have different names for the subwindow and the [struct] inside it. 
So what exactly is a "template"?

Ok, so three questions now:
3. In 01.scalars.pd, it also says:
"Data is not persistent. If you save a Pd patch and reopen it, the "data" isn't preserved.
But it is preserved (e.g., plot-help.pd).  Or am I misunderstanding?

Thanks,
Jonathan
