What is the difference in Delphi between using {.$DEFINE VAR}
and {$DEFINE VAR}
compiler directives?
The code originally had a {$DEFINE VAR}
directive in it, then a period was added to turn the directive into a plain ordinary comment without removing the directive, presumably so it can be restored at a later time.
{$...}
is a compiler directive.
{...}
that does not start with {$
is a comment.
