Message Index Listing

Hey y'all,

When you run the message index lister and select a message base, you are 
presented with a list of messages in that base... what is the ini file or 
prompt number to change how that message list is?

I have looked in ansimidx.ini and prompts to see if I can find where to make 
edits, but for the life of me I can't see where to change it. I'm trying to 
make a 132x37 list so expanding the width of each column or moving a column 
over a bit. I've managed to do the actual message base list but when you go 
into a base it's that screen I have trouble finding the file to edit for it's 
layout.

Please can someone put me out of my misery and help me find this elusive file? 
=)
Thanks in advance!
