valuethe value of expression
Value returned: the value of the expression after HyperTalk evaluates it There is no limit to the number of characters that the value can have as its argument. When the argument of value is a multitoken literal expression, the expression evaluates to itself: put value("HyperCard 2.2") yields HyperCard 2.2
Examplesput the value of the clickChunk into theClickedText the value of "3" & "+2" -- returns 3+2 the value of ("3" & "+2") -- returns 5

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.
