Counting data items

The mqCountItems call counts the number of user items, system items, or both, that are stored in a data bag, and returns this number. For example, mqCountItems( Bag, 7, ...), returns the number of items in the bag with a selector of 7. It can count items by individual selector, by user selectors, by system selectors, or by all selectors.

Note: This call counts the number of data items, not the number of unique selectors in the bag. A selector can occur multiple times, so there might be fewer unique selectors in the bag than data items.
