If you are trying to get the value from a variable and the variable's name
is dynamically created.

For example I have 3 variables:

foo0 = "zero"
foo1 = "one"
foo2 = "two"

i = 0
while(i < 2)
trace("foo" & i & " = ")
trace(eval("foo" & i))
i = i + 1
loop

Note the first trace is evaluated to foo0 (or 1 or 2), while the second
trace with the eval is evaluated to (zero, one or two).

This is used a lot if you are faking arrays in Flash 4.


Hope that helps...
