Subject: Re: Arrays with records as objects

Thanks for all the advice.

Bear in mind though, that in some cases (not all!) the poor coding was 
simply because I cut and pasted a line (ie the build of addr_rec) - I 
wouldn't write code like that in working code. I'll make notes though to 
the best practice in my test examples (actually it's now one example as 
I thought I'd bolt all the examples into one module and use arguments 
and a case to drive it - just to see how arguments and case worked! - 
once I know how to create libraries, I'll split them back out again!)

What I've found odd so far is that Ruby appears to have multiple ways of 
doing the same thing - so as you say, I could write:
line[i] = some_rec
or
line << some_rec
(assuming the index points to the next empty slot)

..and the examples don't appear (so far) to explain the why's and 
where's and then best practices.

Ditto for iteration.


All this is my fault , as I was up to array handling, and then googled 
something I didn't quite follow - and ended up at a site with a 'todo' 
example that I thought would be good as a mini test module. So I jumped 
ahead of myself and started faffing around with that and then hit 
records in arrays etc.

Such is the learning curve.

Thanks for your patience.
