You use it when you are dynamically "building" the name of a variable.
for example... say you have a ton of variables,

foo1, foo2, foo3, etc.

and you have a variable num. Which say, is 2.

Say you wanted to find out what the variable fooX was, where X is the value
of num.

Just building the string "foo"&num wouldn't work... its just a string. So
you would use eval!

eval("foo"&num)

would find the value of that variable.

Subject: FLASH: When to Use (Eval)?


I'm looking for a clear explanation of when to use (Eval) and when not to
use it. Can someone come up with a clear rule I can pass along to my
students?

Thanks.
