{ This is a left marginal comment. }
var i : integer; {This is a trailing comment}
j : integer; {This is a right marginal comment}
k : array [ 1..10] of array [1..10] of integer; {Marginal, but past the margin}
An aligned, multi-line comment

i := 1; {Trailing i comment}
{A left marginal comment}
j := 1; {Right marginal comment}
