you wouldn't have to code it twice using CFIF
just have the CFIF around the checked parameter
<input type="checkbox" name="cbox" value="yes" <cfif x=y>checked</cfif>>

Subject: RE: Which is quicker
The one place I've found that I really like the IIF is to use it in
areas like the following code sample:
<input type="checkbox"
name="#REQUEST.cReorderFormArtPrefix##ReorderJob.ljob#"
value="Yes"
#IIF(laReorderJobs[lnLoop][REQUEST.cReorderFormArtPrefix] NEQ "",
DE("CHECKED"), DE(""))#>
I found using it this way is much more readable in my code then using
<CFIF> and having to code the almost identical <INPUT> tag twice with
only the "CHECKED" option in or out.

Really? I'm getting about 50 and 150ms respectively. So for me while
iif()
is slower it's only one hundredth of a millisecond difference i.e. way
below
anything I'd worry about. So it's a style thing then.

You may get these results due to use of de(), run this code, which I
think
is more fair:
<cfset temp = getTickCount()>
<cfoutput>
<cfloop index="i" from="1" to="10000">
<cfif i mod 2>1<cfelse>2</cfif>
</cfloop>
</cfoutput>
<cfoutput><h1>#temp-getTickCount()#</h1></cfoutput>
<cfset temp = getTickCount()>
<cfoutput>
<cfloop index="i" from="1" to="10000">
#iif(i mod 2, 1, 2)#
</cfloop>
</cfoutput>
<cfoutput><h1>#temp-getTickCount()#</h1></cfoutput>
I got 15 - 16 as results for both of them with some variations both ways
which I discard as noise.

My test indicates iif() is about 400% slower. But the real issue is
code
readability. If you think it's more readable in any or all
circumstances,
I
say go for it. Personally, I think this example demonstrates it is
less
readable. There are probably other example that show it in a better
light.
Here's my sample:
<cf_stopwatch>
<cfoutput>
<cfloop index="i" from="1" to="10000">
<cfif i mod 2>!<cfelse>?</cfif>
</cfloop>
</cfoutput>
</cf_stopwatch>
<cf_stopwatch>
<cfoutput>
<cfloop index="i" from="1" to="10000">
#iif(i mod 2, de("!"), de("?"))#
</cfloop>
</cfoutput>
</cf_stopwatch>

I don't know why people don't like iif (immediate if), it is as quick
as
cfif and takes only one line. For simple things, like "if x < y print
true
else print false", I think using iif makes code shorter without
sacrificing
clarity and speed.
If you don't believe iif is fast then I encourage you to write a small
test
and see for yourself.

cfswitch is both quicker and more elegant. The only downside is that
it
doesn't handle dynamic values.
Iii() is one of those functions, like evaluate(), usage of which is
generally discouraged.

Subject: Which is quicker
Can I get a little advice on which is quicker or which is the
preferred
way
of programming - there are 8 items to select from:
CFIF, CFCASE or IIF
TIA!
