If \fIdata-expr\fR, \fIoffset\fR or \fIlength\fR evaluate to null,
then the result is also null. If \fIoffset\fR is greater than or
equal to the length of the evaluated data, then a zero-length data
-string is returned. If \fIlength\fI is greater then the remaining
+string is returned. If \fIlength\fI is greater than the remaining
length of the evaluated data after \fIoffset\fR, then a data string
containing all data from \fIoffset\fR to the end of the evaluated data
is returned.
