value
the value of expression
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 Examples

the value of "3" & "+2" -- returns 3+2
the value of ("3" & "+2") -- returns 5Demo Script

expressionHyperTalk DefinitionAny 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 DefinitionAny series of words that has a value.
