the 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


put the value of the clickChunk into theClickedText

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

Demo Script

on talkAboutValue
   select last line of me
   answer "The last line of field “Demo Script” is:" & return &&¬
   last line of me & return & return &¬
   "The value of the last line of this field is:" & return &&¬
   the value of last line of me
 end talkAboutValue

 2 * (3 + 6)/4


HyperTalk DefinitionAny HyperTalk expression. All expressions evaluate to text, a number, or a constant.

For example:

"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.
