goto LABEL
Finds the statement labeled with LABEL and resumes
execution there. Currently you may only go to
statements in the main body of the program that are
not nested inside a do {} construct. This statement
is not implemented very efficiently, and is here
only to make the sed-to-perl translator easier. I
may change its semantics at any time, consistent
with support for translated sed scripts. Use it at
your own risk. Better yet, don't use it at all.
