Using cfloop to intialize variables

[philh]

<cfloop index="i" from="1" to="29">
<cfset "Q#i#1" = 0>
<cfset "Q#i#2" = 0>
<cfset "Q#i#3" = 0>
</cfloop>
<cfloop index="i" from="1" to="29">
<cfset thisvar = #evaluate("'Q'&i&'1'")#>
<cfoutput>#evaluate("'Q'&i&'1'")# - #evaluate(thisvar)#<br></cfoutput>

</cfloop>

Possibly because it's invalid syntax, I should think ;-)

Try this:

<cfset "Q#i#1" = 0>

While this method did create all the variables, instead on each variable equaling zero, it equals it's name. So, the value of variable Q11 is Q11, value of Q12 is Q12, etc.

You don't need to do this.

<cfset thisvar = variables["Q#i#1")>

> <cfoutput>#evaluate("'Q'&i&'1'")# - #evaluate(thisvar)#<br></cfoutput>

Similarly here.

I would say that about 95% of the time that you might think you need to use
evaluate(), you really don't need to.
