SPACE

 ──SPACE(string─┬─────────────────────┬─)──────
                  └─,──┬───┬─┬────────┬─┘
                       └─n─┘ └──,pad──┘

SPACE formats the blank-delimited words in string with n pad characters between each word. The n must be nonnegative. If it is 0, all blanks are removed. Leading and trailing blanks are always removed. The default for n is 1, and the default pad character is a blank.

Here are some examples:

SPACE('abc  def  ')          ->    'abc def'
SPACE('  abc def',3)         ->    'abc   def'
SPACE('abc  def  ',1)        ->    'abc def'
SPACE('abc  def  ',0)        ->    'abcdef'
SPACE('abc  def  ',2,'+')    ->    'abc++def'
