A lot of functions use const pointer arguments. If I have a non-const
pointer, it is transparently made const when I pass it to the
function, e.g. char * -> const char *. However, this does not appear

void test1 (char **value)

collect a line of a string (with numbers, letters, dashes) into each
variable. For just numbers, it's relatively easy:
ifstream fout("s1.in");
for (a=0; a<17; a++) {
fout >> data;
cout << data <<...

Why is the addition here adding the number as a string but the subtraction
works fine?
function boxchange(box) {
iv= dbform.ut.value
