[REBOL] [REBOL] How to write text one line at a time

[tjohnson]

I would like to open a text file.
like FILE *f = fopen("text.txt","w")
in C.

Then I would like to write text one string
at a time. 
Then close it.

I'm honestly not clear on how to do this.

I looked at RebolGuide\users\filwrite.html
and I don't seem to see any documentation
as to how this is done. 

Pretty basic stuff,
info on how and where to find documentation
would be appreciated.

thanks
