in a thread off-list i commented on the use of a function. here's what i
said:
yes, it's just like that. i could wrap a function around the logic. and
sometimes i use that trick.
the downside to that is access to globals. for many of my scripts there's a
common pattern:
1 get set up.
2 process inputs, checking and preparing data for use 3 and 4 or aborting to
an error handler at the end of this section (which is what the breaks all
jump to) if there's a problem with the input.
3 do some work
4 prepare an output page
in this scheme, it's convenient if 2, 3 and 4 all have access to the same
namespace, so i don't usually use the function approach.
