Re: repeating

[Aleksander Saidi]

Dear Cliff Bender,

Try something like that :

repeat, write('w00t: '), read(Input),(Input=stop,!,stop;write('I\'m 
terribly sorry. I don\'t understand the meaning of that sen'),nl).

The thing is the 'cut' before stop.

You may also write :
repeat, write('w00t: '), read(Input),(once(Input=stop),stop;write('I\'m 
terribly sorry. I don\'t understand the meaning of that sen'),nl).

'once' is better since it has its own cut.

OR :
repeat, write('w00t: '), read(Input),(Input=stop -> stop;write('I\'m 
terribly sorry. I don\'t understand the meaning of that sen'),nl).

if-else (given by '->') is equivalent (you better put '()' around the 3 
parts of a if-the-else)

Regards.

read_line is replaced by read.
