As far as I can see the two expressions are the same, in fact the brackets
in this case are redundant
ie you could write
if DateSwitch and not RxCheckListBox6.Checked[2] then
CheckFileExist(VCLzip1.zipname);
Not knowing the exact details there are situations where you can get in
trouble with
Delphi Short circuiting its boolean eval, ie if DateSwitch was a function
that performed some other
operation and you relied on that to be called
