Subject: Programming External azAZ09-5 without filter

Hi all,

First, sorry about my newbie question.

I'm trying to program an external mode of azAZ09 charsets of 5 length.
I want generate words cleanly, so i won't need use filter function() and earn time.
It's possible that?

My try is next:
[List.External:azAZ09-5]
int length, i;

void init()
{
 length=i=5;

 while (i--)
     word[i]='0';

 word[length]=0;
}

void generate()
{
 i = length - 1;

 while (++word[i] > 'z')

   if (word[i]<':' || word[i]>'@')
	if (word[i]<'[' || word[i]>'\'')

		if (i)
			word[i--] = '0';
 		 else {
			word = 0; 
			return;
		}
}

void restore()
{
 length = 0;

 while (word[length])
    length++;
}This produce 5 length words but can't avoid not alphanum characters...
Where is my mistake?

Thank you in advance...
Rubén Lara
