[REBOL] Re: Returning true when parsing a blank line

From: arolls:bigpond:au at: 6-Feb-2001 16:17

This prints true/false at the beginning of each line,
indicating whether this line had nothing (none) in it.

 x: read/lines %file.txt
 foreach line x [print [parse line [none] line]]

Do you want to combine other parse rules with the
'none possibility?

Otherwise you can test using [empty? line] or [line = ""]
