[Oberon] Question about Oakwood guidelines and design choices

[Robert Doiel]

Good Morning,

I was looking at the Oakwood Guidelines this morning trying to sort out 
why an implementation of `Out.Real()` might only accept a single 
parameter versus two (like `Out.Int()` ). The Oakwood guidelines I am 
reading in PDF form are from Oct. 20, 1995 (URL 
https://www.math.bas.bg/bantchev/place/oberon/oakwood-guidelines.pdf 
downloaded on 2021-06-06) and indicate that two parameters are expected.

Next I looked at how the Oxford compiler implemented Out and saw that it 
was a very thin wrapper on Files using STDOUT instead of a user supplied 
file handle.  That makes complete sense to me, at least from a POSIX 
point of view.  But Files WriteReal() in Oakwood on;y has one 
parameter.  Does anyone know the history behind why Oakwood as to why 
Out.Real() and Files.WriteReal() would be different?

I noticed in Native Oberon 2.3.6 that Files.WriteReal() does have two 
parameters. Just curious to know the story behind the evolution from 
1995 to Native Oberon 2.3.6.

All the best,

Robert Doiel
