value

Type

function

Summary

Returns the value of an expression.

Syntax

the value of <expression>

value(<expression> [, <object>])

Description

Use the value function to evaluate an expression, or to force LiveCode to evaluate an expression within a statement.

    ask \"What do you want to compute?\"
    answer it && \"equals\" && the value of it

If you specify an object, references to me in the expression are treated as references to the object. However, other object references are treated as though the handler were in the current object's script. For example, "button 3" refers to button 3 on the current card, not the card where the object is located.

If the expression is a single string, then even if it is enclosed in quotes, LiveCode attempts to evaluate its contents instead of treating it as a string literal. This means that you must be careful about string literals that contain operators such as "and".

Parameters

Name	Type	Description
expression		Any expression.
object		Any object reference.
