Behaviour of reset and extend on text file

I'm not sure what the correct behaviour should be in the attached program, but GPC's behaviour is different from the previous extended Pascal compiler I used (I'm not saying that the previous compiler was right). The previous compiler allowed one to write to a text file that had been opened with 'reset' and then 'extend'ed. GPC says: ./daj13: cannot write to read only file `daj13.pas' (error #422) ===== program daj13(input,output); var f:text; begin reset(f,'daj13.pas'); extend(f); writeln(f,'extra text'); end. -- David James mailto:david@tcs01.demon.co.uk Special Stage Rally results archive <URL:http://www.tcs01.demon.co.uk/>
