How to edit Text in Memo?

Question

I wanted to use procedure Delete(Memo.Text, index, count) (or similar Insert). But I get message 'Constant object can not be passed as var parameter'. I know I can select text and to use this procedures with Seltext. But this way is a bit uncomfortable. Is there anything easier?

Answer 1

Text is a property rather than a variable. And Delete requires a variable. So you need to use a temporary variable. For instance

var
  str: string;
.... 
str := Memo1.Text;
Delete(str, index, count);
Memo1.Text := str;
