Delphi regular expression syntax (3): matching range

// [A-Z]: match all uppercase letters var REG: tperlregex; begin REG: = tperlregex. create (NiL); Reg. subject: = 'codegear Delphi 2007 for Win32 '; Reg. regEx: = '[A-Z]'; Reg. replacement: = '◆ '; Reg. replaceall; showmessage (Reg. subject); // return: ◆ ode ◆ ear ◆ elphi 2007 for ◆ in32 freeandnil (REG); end;
