People,

Thanks to the people who responded - I looked at everything but nothing 
really suited what I was trying to do but see below for some progress 
that I made and another question:

I found that I could use sequential "ifs" instead of nested "ifs" by 
using "exit" statements in each "if" block - the script is processing 
incoming mails and can exit when a mail has been satisfactorily 
classified.  I still have something like this:


lots of code
if block - small
lots of code
if block - small
if block - large
if block - small
if block - large
.
.
etc


What I want is to be able to see the whole logic of the program in 
about 25 lines (ie one screenfull of code - ie all the "if" statements) 
- I could probably use standard methods for the repetitive small "if" 
blocks but for the large "lots of code" and "if block - large" I 
definitely can't.  Is it possible that a method can be forced to NOT use 
local variables? - then I could replace the large blocks with these 
sorts of methods.

Thanks,

Phil.
