VB doesn't have a direct way to do that. One option:

dim c as collection
set c=new collection
c.add il_temp,"il_tem p"
msgbox c.item(test)

Re: Value of a &quot;string&qu ot;

I see this type of question get asked a lot and I'm at a loss to understand
why. I've been programming since 1981 and have yet to run into a need to do
this type of indirection. After all, it could only be used successfully by
the programmer him/herself... I mean, you can't expect the user to know to
type in "ll_temp" into a TextBox in order for the program to go and get the
value of PI hiding underneath it. So, if it would only be used by the
programmer internally to his/her program, why not just use the variable
ll_temp directly? Or, if there is some kind of variability required (having
trouble imagining what), simply use a Select Case statement. And if needed
more than a couple of times, set up a function that runs the Select Case
instead so that you can pass in an argument indicating you want the value of
PI. Maybe make the function take a String argument so "ll_temp" could be
passed in even.<g>

Re: Value of a &quot;string&qu ot;

VB doesn't do this kind of thing....also called macro substitution...

Best way is to follow Bob's example.

I've dealt with a couple of cases where it would have come in handy; the
controlling data (e.g. 'il_temp') was coming from a database or some other
external source and the v alues to be used and/or actions to be taken depend
on one or more of the input fields... it's not something I've run into often
and I think many of the people asking it are doing so due more to limited
experience with alternate methods than a real need for what they are asking
for.
