A CR-LF delimited list of words or entries to examine.
The word(s) to find.
Default = whitespace (e.g. a space, tab, or CR-LF character). A character string that separates words or entries.
Returns all words not included in the exclude list.
Returns Words (case sensitive) that are not in the exclude list.
WORD_SUBTRACTC() removes all of the words or entries in a list of of words using a case-sensitive comparison. The words to remove are defined as a CR-LF delimited list. The WORD_SUBTRACTC() function is typically to remove one list of CR-LF delimited words from another list of CR-LF delimited words.
For case-insensitive comparisons, use WORD_SUBTRACT().
dim list1 as c =<<%str% ONE two THREE four %str% dim list2 as c =<<%str% one TWO three FOUR %str% dim removelist as c =<<%str% one two three four %str%
In the first case, the delimiter of list1 is assumed to be a whitespace character, so the operation succeeds. In the second case, where the delimiter of list1 is specified to be CR-LF, the operation fails.
? word_subtractc(list1, removelist) = ONE THREE ? word_subtractc(list1, removelist, crlf()) = ONE two THREE four
In both cases, the operation succeeds because list2 is delimited by CR-LF characters.
? word_subtractc(list2, removelist) = TWO FOUR ? word_subtractc(list2, removelist, crlf()) = TWO FOUR
