Returns a string of length length
with string centered in it and with
pad characters added as necessary to make up
length. The length must be a positive whole
number or zero. The default pad character
is blank. If the string is longer than length,
it is truncated at both ends to fit. If an odd number of characters is truncated
or added, the right-hand end loses or gains one more character than the left-hand
end.
Here are some examples:
Example 7.18. Builtin function CENTER
CENTER(abc,7)--> " ABC "CENTER(abc,8,"-")--> "--ABC---"CENTRE("The blue sky",8)--> "e blue s"CENTRE("The blue sky",7)--> "e blue "
Note
To avoid errors because of the difference between British and American
spellings, this function can be called either CENTRE or CENTER.
