Test

true? str.match(/string$/)
{ p "Ends with 'string'" }
false? str.match(/^You/)
{ p "Does not start with 'You'" }
</lang>
Substitute
<lang brat># Substitute in copy
str2 = str.sub(/ a /, " another ")
p str # original unchanged
p str2 # prints "I am another string"
# Substitute in place
str.sub!(/ a /, " another ")
p str # prints "I am another string"
# Substitute with a block
str.sub! /a/
{ match | match.upcase }
p str # prints "I Am Another string"
