Hi Wade.
'Dot-Equals' is valid construction, it is a form of concatenation...
eg.
$say="hello ";
$say .= "world. <br>";
ECHO $say; [echos Hello World.]
The advantage is that you can 'collect' additional statements as you
execute a routine and then pass that on at the end as one variable...
Such as "Welcome, JOHN SMITH to your THIRTEENTH tri-mester, Your
PASSMARK was 50%. WELL DONE".
where as, another user executing the same statement, with different
conditionals might get "Welcome, ANNE MARSHALL to your ELEVENTH tri-
mester, Your FAILMARK was 48%. PLEASE VISIT YOUR TUTOR BEFORE
CONTINUING".
I guess there are many ways of resolving the above example, but for
some, concatenation using dot-equals seems to work well.
