Values returned: A non-negative integer equal to one of the following: - total number of buttons or fields on the current card or background
- total number of parts (buttons and fields combined) on the current card or background
- total number of marked cards, cards in a specific background, cards in an entire stack, or backgrounds in a stack
- number of all the windows (including built-in palettes and external windows) in HyperCard
- number of menus in the menu bar or the number of menu items in a specified menu
- total number of characters, words, items, or lines in the value of any HyperTalk expression (treated as text)
Examples-- Count the menu items in a menu: the number of menuItems of menu 2 the number of menuItems of second menu the number of menuItems of menu "File" -- Count the number of objects: the number of card fields the number of background buttons the number of cards the number of cards of this background the number of backgrounds the number of parts the number of background parts -- Count the number of chunks in text (including containers): the number of chars in card field 2 the number of lines in the stacksInUse -- Do something based on the number of cards: repeat with i = 1 to the number of cards of this background statements end repeat repeat with i = 1 to the number of marked cards statements end repeat

bkgndA HyperTalk expression that identifies a background by name, number, or id, using one of the following forms: bkgnd id posInteger bkgnd text -- name bkgnd posInteger -- number ordinal bkgnd position bkgnd
For example: bkgnd id 3894 bkgnd "Index" bkgnd 1 prev bkgnd previous bkgnd next bkgnd this bkgnd first bkgnd last bkgnd middle bkgnd any bkgnd
From within a background script, the term me refers to that background. When a background receives a the message [the] target, that message is referring to the background. See also: card menuAn expression that evaluates to one of the following: menu text menu posInteger ordinal menu
For example: menu "File" menu 2 second menu
chunksOne of the following: characters chars words items lines
expressionHyperTalk Definition Any HyperTalk expression. All expressions evaluate to text, a number, or a constant. For example: true sin(90) "this is" && it (3+2) = 5 the heapspace div 1024
Note: Formally, HyperCard distinguishes between factors (simple values) and expressions. The difference between factors and expressions matters only if you like to drop parentheses. Most functions take factors as their parameters, which is why length of 3 + 5 returns 6 and length of (3 + 5) returns 1. In short, always use parentheses to group things the way you want them to evaluate, and you won’t have to worry about the difference between factors and expressions. AppleScript Definition Any series of words that has a value.
