§ Split(expression,delimiter,count,comparetype) takes a string and
splits it into an array of strings. expression is the string to be split up.
If
expression is zero length. Split returns an array of no elements,
delimiter is a string that indicates what is used to separate the sub-strings
in expression. This is optional; by default the delimiter is the space. If
delimiter is zero length (""), an array of one element consisting
of the
whole string is returned, count is used to specify a maximum number of
sub-strings to be created. The default for count is -1, which means no
limit. If comparetype is 0, a binary comparison is performed, and
uppercase letters are distinct from lowercase letters. If comparetype is 1,
a
textual comparison is performed, and uppercase and lowercase letters are
the same. comparetype is only useful when the delimiter you have chosen
is a letter.
§ Join(stringarray,delimiter) does just the opposite of Split. It takes
an array of strings and joins them into one string, using delimiter to
separate them. delimiter is optional; the space is the default.
