Subject: Re: Arrays with records as objects

Robert,
Thanks for the informative replies - very much appreciated.

I am 'playing'/'learning' at the moment - so what I have been doing is 
taking base examples and then adding how I could use them in the 'real 
world'.

In an earlier array example, I had used the record Openstruct structure 
as:
            # -- This is my test to see how arrays can be indexed.....a 
five element array
            # -- for names and address/post code
            addr        = []

            for i in 0..5
                addr_rec        = OpenStruct.new
                addr_rec.name   = "Cust#{i+1}"
                addr_rec.line1  = "C#{i+1}Line1"
                addr_rec.line2  = "C#{i+1}Line2"
                addr_rec.line3  = "C#{i+1}Line3"
                addr_rec.line4  = "C#{i+1}Line4"
                addr_rec.pcode  = "C#{i+1}PCode"
                addr[i]         = addr_rec
            end

            for i in 0..(addr.length-1)
                `zenity --info --title="My Array" --text="Each Array 
Element:\n#{addr[i].name}\n#{addr[i].line1}\n#{addr[i].line2}\n#{addr[i].line3}\n#{addr[i].line4}\n#{addr[i].pcode}"`
            end

So, because that seemed to work ok,  I then wanted to try to represent 
the TodoList  file line contents as a 'record' (in general, that is how 
I'm used to handling file data). Hence then getting the 'line' record 
into the array.

In between postings though, I did remove the record structure, and made 
the item three separate instance variables again.
So I think I'll create two versions of this - the single variables and 
record structure options.

All the STDOUTs are my debug lines (as well as the main zenity system 
calls) to see what is going on.

The 'toggle' on the status is driven by a zenity window - a checkbox 
just marks 'Done' - but I see what you mean.

Thanks for the info on the ternary operator - and I'll look into logger 
calls and create an example for that!


Is there a separate forum that you know of for complete Ruby newbies 
like me?

Thanks again for your help.
