Use 'wrap...
view layout [field 50x100 "The rain in Spain is wet..." wrap]
Though 'area instead of 'field is normally used when you want a
multi-line box. You still need wrap to get word-wrapping though.

abc^/def
or "abc^(line)def".
The "^" is the escape character, so, when used at the Console...
>> print "abc^/def"
abc
def
>> print "abc^(line)def"
abc
def
>> print "abc^-def"
abc def
>> print "abc^(tab)def"
abc def
>> print "abc^^def"
abc^def
>> print "abc^(41)def"
abcAdef
and so on. The number in the last one there is in hex, not decimal.
Look in the Core Guide (it's on the REBOL site) in the Other Values
section for Character to see the other escape characters.
