platform() = MacOS (9 with ascii(13) or X with ascii(10))?

[Kee Nethery]

Regardless whether CR is platform specific, I know that Mac OS 9 uses 
a ascii(13) to delimit lines and I assume revolution honors that on 
Mac OS 9. It appears that revolution in Mac OS X uses ascii(10) to 
delimit lines.

Since platform() is supposed to return "MacOS" for both versions of 
the MacOS and because the two platforms appear to use different line 
endings in Revolution ... how do I tell whether I need to convert 
line endings from ascii(13) to ascii(10) or leave them as ascii(13)?

How do I know which MacOS I am on given that Revolution appears to 
treat them differently?
