Procedures and repeat-until command are includeded in MP.
As said I'm new to MP and Pascal itself.
Sure we can do the same without this command, especially if it's so dangerous.
I don't know why some compilers includes Labels + GOTO + more Pascal commands and others don't.
But if MP could do that (without crashing or generating bugs) it would not be such a crime!
For a beginner as I am, It would be interesting to have a complete list of MP commands; somewhere I read the one in MP help file is uncomplete.
P.S. Thank you for your answer
