by the way, b4 going into the for loop 'size' is 28, and and 'ptr1' is 18. so y
do u say ptr1 will never be > 1?. this is what the for loop looks like and as u
can see 'pass' is being decremented

for (pass=rx_str[ptr1+1]; ptr1<size && pass; ptr1++) {
     rx_str[ptr2]=rx_str[ptr1];
     ptr2++;
     pass--;
}

so it would make sense to check that pass stays above 0 rather than ANDing the
values of size and pass together like u suggested.
