In following example, if Options['LoopSelect'] is not 'true' or
'false' then EConvertError will be raised.
I'd like to treat '' as false.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i function
TBlockStart.getLoopSelect: boolean;begin   try      Result :=
StrToBool(Options['LoopSelect']);   except      Result := False; 
 end;end;

Actually, there is StrToBoolDef for this:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i function
StrToBoolDef(const S: string; Default: Boolean): Boolean;

By the way, there are global arrays TrueBoolStrs and FalseBoolStrs, in
which you can specify acceptable values.

function StrToBoolDef(const S: string; Default: Boolean): Boolean;

This really helps, and good enough. Thank you very much.
