Cart Masks Explained

Print this Topic Previous pageReturn to chapter overviewNext page

Cart masks are used to identify carts (audio files) that might be grouped together. A cart mask must be exactly 4 (four) characters in length. Mask entry dialogs will not allow entries that are too short and will not accept more than 4 characters entered.

The "?" (question mark) is a "wildcard", meaning a letter or number is valid in its position in the mask. This is the only wildcard character allowed for a cart mask - all other characters will be interpreted literally.

Valid characters for a cart mask, besides the "?" (question mark) include the letters A .. Z, the numbers 0 .. 9 and the characters "{" and "}".

A valid cart mask will include one or more "?" characters (although it doesn't have to) and other letters or numbers that match up with cart types that you wish to have grouped together. Examples of valid cart mask include:

Mask

Result

C???

Carts beginning with the letter "C" and any 2nd, 3rd and 4th character will be included.

PR??

Carts with the first two characters of "PR" and any 3rd and 4th character will be included.

?R??

Carts with any first character, a second character of "R" and any 3rd and 4th characters will be included.

Z?A?

Carts with a first character of "Z", any 2nd character, a third character of "A" and any 4th character will be included.

A cart mask of "????" is the same as saying "any cart number is valid" and should not be used, as all carts would match such a mask.

Combining a number of cart masks for use in a cart category will group all carts that meet at least one of the cart masks. For instance, you could have a filter called "R Carts" that has 4 cart masks - "R???", "?R??", "??R?" and "???R". The result of using this cart filter would be that every cart in the inventory that has the letter "R" in any character position (1st, 2nd, 3rd or 4th) would be a match.
