Help me simplifying the code

Using Arduino Programming Questions

Total newbie here, I'm trying to symplify this code :

void loop(){

   char keyPress = keypad.getKey();

	if ((keyPress == '0') || (keyPress == '1') || (keyPress == '2')|| (keyPress == '3')|| (keyPress == '4')|| (keyPress == '5')
	|| (keyPress == '6')|| (keyPress == '7')|| (keyPress == '8')|| (keyPress == '9')&& pos < 13){

	//blabla

	}
}

I'm thinking about making a function and call it like :

if(Name_of_Function){
//blabla
}

But I don't know how to do it. Any help ?

How about

if (Name_of_Function (keyPress))

?

It's already in the language...

 if ( isdigit(keyPress) and pos < 13) { ...

    if (pos < 13)  {

        case '0':
        case '1':
        case '2':
        case '3':
        case '4':
        case '5':
        case '6':
        case '7':
        case '8':
        case '9':
                //blabla
            break;
        case '*':
        case '#':
            break;
        }
    }
}

Something like:

	if ((keyPress >= '0') &&  (keyPress <= '9') && pos < 13) {

or

	if (isDigit(keyPress) && pos < 13) {
