how compare string integer using while loop in pascal?
this:

var destination:string; while (destination>'11') begin     writeln('error');     write('destination number');     readln(destination); end;

you have convert destination integer:

program project1;  uses sysutils;  var   converted: integer;   destination: string;  begin   converted := 12;   destination := '';   while (converted > 11)   begin     writeln('error');     writeln('destination number');     readln(destination);     converted := strtointdef(destination, 12);   end; end.
