Hello, is possible that CASE operates with several options?
case 3,5,9:

Code : Tout sélectionner

test_switch():={

	local c; 
	assume(c,DOM_INT);

	DispG; ClrIO; ClrGraph; 

	input("c",c);  

	switch(c){
		case 1:{
			printf("1");
			break;
		}
		case 3:{
			printf("3, 5 o 9");
			break;
		}
		case 7:{
			printf("7");
			break;
		}
		default:{
			printf("not is 1, 3, 5, 7, 9");
			break;
		}
	}

	Pause; DispHome; 
	return Done;
}:;

Code : Tout sélectionner

sin_titulo_05():={

	local c; // definir la varible de consulta
	assume(c,integer);

	DispG; ClrIO; ClrGraph; // inicia la consola entrada/salida, luego limpiar pantalla

	input("c",c);  


	switch(c){
		case 1:{
			printf("1");
			break;
		}
		case 3:{nop}
                case 5:{nop}
		case 9:{

			break;
		}


		case 7:{
			printf("7");
			break;
		}
		default:{
			printf("no es 1, 3, 5, 7, 9");
			break;
		}
	}

	//Pause; DispHome; // cierra la consola entrada/salida
	return Done;

Xcas case does not follow exactly the same rule as in C, if there is no break in a case then the next case are not taken but the default case is executed. In other words, put a break unless you know exactly what you do.
