The getenv() routine will return -1 if the environment variable CONTENT_LENGTH
doesn't exist. If it does exist, a string will be returned.
Since CONTENT_LENGTH is supposed to be a number, we use value() to convert the
string to a number.

value() also returns a sequence of length = 2, where the 1st element is an error
code and the 2nd is the actual number value.

Hence the 2 error checks.
