According to the docs the with statement when used with mulltiple<br>
objects only works with the last parameter.<br>
<br>
<br>
The statement<br>
<br>
With A,B,C,D do Statement;<br>
<br>
is equivalent to<br>
<br>
With A do<br>
With B do<br>
With C do<br>
With D do Statement;<br>
<br>
--<br>
<br>
I thought that if all the objects have the property the statement would<br>
apply to them eg.<br>
<br>
<br>
with Label1, Label2, Label3 do<br>
Caption = 'Text'.<br>
<br>
I thought all the 3 labels would have the caption set, but only Label3's<br>
caption is set. Is this a difference between Delphi's Object Pascal and<br>
FreePascal, or has Delphi's Object Pascal always worked in the same manner?<br>

It has always worked in this manner. It's just for abbreviating typing, not for combining properties. (and then the with-variant with multiple elements is even more seldomly used than the single-element one...)<br>
<br>
