Remember, lists are like strings. As with strings, you can use the beginsWith, contains and endsWith operators on lists. In previous versions of Frontier, it was possible to create lists and query them using the built-in verbs putAppleListItem and getAppleListItem. They are still supported in Frontier 3.0, so if you have scripts that use these verbs, you're in good shape. But the new syntax for lists is much more convenient and sensible for scripts that run in Frontier 3.0 and beyond.
Records are another new data type.
Records are a lot like lists, the main difference is that each element of a record has a 4-character name. This effects how records are created, added and subtracted. There are no rules about the types of the element. In one record, the element named 'age ' could be a string value, in another record it could be a number. Many applications use records in their Apple Event interfaces, so records can be convenient for passing information around between apps.
