In general, for static variable names, you should use cfset, or
better yet an assignment statement in a cfscript block. Your best
use for SetVariable is when you have a dynamic name for the variable.
Hopefully an example will illustrate:
<!--- This is good: --->
<cfset Whatever1 = 42>
<cfset Whatever2 = "Life">
<cfset Whatever3 = "Universe">
<cfset Whatever4 = "Everything">
<!--- This is better (Should be Faster) --->
<cfscript>
Whatever1 = 42;
Whatever2 = "Life";
Whatever3 = "Universe";
Whatever4 = "Everything";
</cfscript>
<!--- This is when you'd use SetVariable --->
<!--- This sets all the variables named above to 42. --->
<Cfloop from="1" to="4" index="i">
<cfset temp = SetVariable("Whatever#i#", 42)>
</cfloop>
<!--- This is a better way for SetVariable --->
<!--- (At least in this silly case) --->
<cfscript>
/* C++ is my language of choice, so I just LOVE
CFSCRIPT. And the fact that the CFML parser
is faster on CFSCRIPT stuff makes it even
nicer!!!
*/
for(i=1;i LT 5;i=i+1) {
SetVariable("Whatever#i#", 42);
}
</cfscript>
Hope that clarifies. Basically, you should use CFSET or script
blocks 99% of the time. When you have a dynamic situation (stuff
coming from FORM submissions is a common use), then your only
solution would be SetVariable.
