FLASH: random variable typing

[M T]

John, 


The answer is actually A, not D, none of the above.  I certainly appreciate

your help, but you should probably not try to come across as the master expert

all the time.  


I have it working already.  My question is about variable typing.  Roughly

speaking, strongly typed languages require you to declare a variable

specifically as a string or expression, whereas loosely typed languages figure

it out on their own.  The way flash is set up is, to me, a bit illogical.  In

the example I included, whichItem is ALWAYS a variable.  However, in order to

get the value "redpants" into it, you have to present it in quotes

("whichItem").  If it's a variable, it seems to me that it should ALWAYS be an

expression.  However, if the quotes are working as some sort of typing (telling

Flash that the variable you're putting in is a string), then it makes no sense

that when you use trace, you use whichItem in no quotes.  To be consistent,

whichItem should either not be in quotes the 1st time, or it should be in

quotes the 1st time and the trace statement should be trace(eval("whichItem")).



At least that's how I see it. Macromedia?  Anyone else see how the way it's set

up is, in fact, logical?

Hi MT,

> Trace(whichItem)

> RETURNS nothing


> Set Variable "whichItem" = "redPants"

> Trace("whichItem")

> RETURNS whichItem

The answer is D none of the above;


Set Variable: "whichItem" = "redPants"

Trace (whichItem)


RETURNS redPants   which is the value of whichItem

And a Text Field with whichItem as its variable will also display

redPants.


When setting a variable the ABC switch should be on for the top (left

side of the expression) unless it is an expression.

In Trace here you are looking for the value of whichIten so it should be

an expression.
