You CAN evaluate expressions after grabbing them from a database or setting them equal
to a variable:
<cfset a = 5>
<cfset x = "a GTE 1">
<cfoutput>
<cfif Evaluate(x)>
#a#
<cfelse>
a is less than 1
</cfif>
</cfoutput>
However, you won't be able to execute cf tags in this way. The only way to do that,
so far and as far as I KNOW, is the file based writing/including method you mentioned.
