I4GL Variable Initialisation - v4 versus v7

I seem to recall that there was a thread last year regarding the differences between I4GL v.4 and v.7 with specific regard to variable declaration/initialisation along the lines of "you should always initialise ALL variables" and define them inside a globals file. I also recall the discussion covered the scope of variables and the different way v4 and v7 of I4GL treats these. Could someone out there re-enlighten me as to the known differences between these two as (a) I cannot find the thread despite many DejaNews Power Searches, and (b) we've jst been bitten by the problem !
