check if variable contains number

[oblinez]

while(input(.name$) == "" && (isdigit(.name$))){    input .name$;    }

I want the player to type only letters/words, if it contains any number he will have to type it again without numbers
how can I do that?

	} while (callfunc("ValidateInput", .@string$));
	mes "You pick " + .@string$;
	close;
}

function	script	ValidateInput	{
	.@str$ = getarg(0, "");
	.@size = getstrlen(.@str$);
	for (.@i = 0; .@i < .@size; .@i++) {
		if (charat(.@str$, .@i) != " ") {
			if (!charisalpha(.@str$, .@i))
				return 1;
		}
	}
	return 0;
}

you are my savior!
can you explain your code for me? so that i can learn

how does the first part undestand that returning 1 or 0 must repeat the input or not

is this boolean? callfunc returns 1 or 0, while true it pass, false it fall into condition, that's right?

The function i created will loop over each character of the string and check if that character is a letter or a number. If there is a number then always return 1 else 0.

You can return anything from a function you can leave it empty as well for any reason. I just use 0 and 1 because any !var means 0 and var means something else.
