Quick Coding Question : Which Script am I running?

[keithl]

Help please folks - this one is driving me MAD and I know I'm going to kick myself but...

Q : How can I find out from within a template which script I am running?

I've spent hours, Googling, experimenting, searching but to no avail. I know that within each .php script there is the ledgend -

// #################### DEFINE IMPORTANT CONSTANTS #######################
define('THIS_SCRIPT', 'index');

so it's got as far as the PHP constants - but how do I get at simple info like that from within a template? What I want to do is very simple, basically it's -

<if condition="$?????what_goes_here????? == 'specificscript'">
   this bit of html
<else>
   that bit of html
</if>

Go on, put me out of my misery

Thanks

<if condition="THIS_SCRIPT == 'nameofscript' ">
this bit of html
<else>
   that bit of html
</if> 

That should work...
