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. ## Related Topics |

the length of *expression*

Value returned: the number of characters in the value of the expression length of "Hello world"
length("Hello world")
length of field "Index"
length of myVar
length of 3 + 2 -- returns 3
length of (3+2) -- returns 1

on lengthOfMe
put the **length** of bkgnd field "Demo Script" into numChars
answer "This demo script contains" && numChars && "characters."
end lengthOfMe

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.Version 0.7b1 (March 24, 2022)
