Capitalize a passed variable in email confirmation

[Shiraz]

Hi,

Can anyone show me the simplest way to capitalize a passed variable in the confirmation email?

I'm required to do this to add a payment method to my site. The name of the payment method is currently not being capitalized in the confirmation email, and I have been required to capitalize it.

I've found the relevant mail template in mails/en/order_conf.html, however the word I need to capitalize is encoded in a variable ('{payment}'). I have no idea how to alter the contents of the variable. 

Can anyone suggest an easy fix for this?

Regards,
