Readln and Writeln

[vhotspur]

Readln and Writeln buitin subroutines are a TP extension.

Actually, it is a bit more complicated. Wirth1973 does not mention readln and writeln (but note the eol constant) but they are in ISO7185, sec. 6.9.2.

Does it make sense to support three standards? Or how about making the current -std=wirth into ISO?

[Aspect26]

the std=wirth is actually the iso standard (my bad with the naming, will be changed in later version)
the readln/writeln thing in the iso is itneresting, because these subroutines are not mentioned in the required subroutiens section [here](http://pascal-central.com/iso7185.html#6.6.6 Required functions) and the write/read functions are.

So shall I implement them for the ISO standard also?

See note 1 in 6.6.5.2 File handling procedures. So IMHO they are really part of the standard.
