Like the subject line reads, I've been beating my head against the wall on how to program adding an additional number to a variable of numbers that already exist. what I mean is if I have a variable called set_numbers:
var set_numbers = 10;
now I want to add the numbers 23 to the back end of it, so that now set_number is = 1023, but the numbers being added is off the fly and maybe totally random.
I've tried using an array. even tried str_for_num and str_to_num, inkey and some other things to stack the numbers behind each other. I know there must be a way, but I just can't seem to figure it out. any help would be appreciated. Thanks.

I would suggest to use string for adding the numbers, then convert it to variable. Something like (not tested):
STRING* setNumStr = "10";
void test(){
str_cat(setNumStr, "23");
var number = str_to_num(setNumStr);
}
Maybe it's no the fastest way to do it, but it should work  Edit: check str_cat_num too! Best regards!

A solution with no strings:
int int_glue ( int n1, int n2 )
{
int n2b = n2;
for ( ; n2b>0; n2b/=10 )
n1 *= 10;
n1 += n2;
return n1;
}
void main ()
{
int a = 12345;
int b = 67890;
int c = int_glue ( a, b );
error ( str_for_int(NULL, c) );
}
Salud!
