you should be able to use
a mix of evaluate() and de() [delay evaluate] to execute code in a string.

Let's assume that I really do need dynamic evaluation of CFML in this
particular situation.

That said, say that the dynamic CFML has been configured to be this:

  <cfloop index="i" from="1" to="10"><cfoutput>#i# </cfoutput></cfloop>

I put it into a string and evaluate the string like this:

<cfset s = '<cfloop index="i" from="1" to="10"><cfoutput>#de("i")#
</cfoutput></cfloop>'>
<cfoutput>#Evaluate( s )#</cfoutput>

using the de() function to delay evaluation of the variable i. This produces
the following error:

[Q]Invalid CFML construct found on line 1 at column 1.  
ColdFusion was looking at the following text:
<
The CFML compiler was processing:
< marks the beginning of a ColdFusion tag.Did you mean LT or LTE? [/Q]

I am pretty sure that Evaluate() takes a Coldfusion [i]expression[/i] and not
CFML.

Other ideas?

None that are as simple as writing it to a disk first.  As Adam mentioned, you
also delete the file right after you use it.  
Just out of curiousity, what is your objection to this approach?
[/q]

I do not object to this approach, per se, especially as it seems to be my only
option :). I was just surprised that a function like BlueDragon's "Render" had
not made it into CF by now. In an ideal world, the execution of CFML would be
agnostic regarding the persistence format (e.g. disk or database) of the code
in question. Right now, it's biased toward disk-based persistence.

But, we all know about ideal worlds...

Thanks for all of your help.
