Re: FLASH: Re: random variable typing

[John Croteau]

Hi Guys,


Sometimes it is much easier to understand something and use it than to

explain it. However I think by now being able to explain this variable

equation protocol of Flash I understand it a little better. At least I

think my explanation will make it more clear and I have a better example

:-)


If an item is in quotes it will not be evaluated. If on the left that is

the name of the variable. If on the right then it is a literal string.


So the norm is 

   Set Variable: "Variable" = "StringLiteralValue"

or

   Set Variable: "Name" = "John"


Therefore the variable Name has its value set to the literal String

John, quotes signifies a literal string on the right and a literal

variable on the left.


If the left is not a literal variable then it is a 'variable of the

variable'. Then the Name on the left is not being set to the equal the

right side of the equation, but rather the value of the variable Nmae

(on the left) will be set to the value on the right.


So in the following:

Set Variable: "Name" = "FirstName"

Set Variable: Name = "John"


Name      --> FirstName

FirstName --> John


Literal Variable - a variable on the left side of the equation in a Set

Variables action that is enclosed in quotes. A literal variable is the

actual name of the variable and is only required to be in quotes (in

Flash) when on the left side of the equation. If you do not enclose a

variable on the left side (Variable Box) of a Set Variables equation

then the variable entered in the box is not the variable of the Set

Variable equation. The value of the entered variable name will be the

actual left hand variable for the equation.


Without seeing the example this is very difficult to understand and if

anyone can improve the wording please let me know.


This is a bit difficult to understand at first but makes Flash Set

Variable equations much more flexible because you can have both sides of

the equation being evaluated in a single expression.
