My instict is that switch/case would be faster since it seems to be a "si= ngle" operation vs 100=20 [showif] operations, but it is untested and based on nothing but my own b= uest guess.

I got this one from someone on the list: Wrap all "line-breaky" code like this: [getchars start=3D1&end=3D&trim=3Dboth] [grep search=3D[%0D%0A][%0D%0A%09]*&replace=3D%0D] ... your line-breaky code goes here ...
