1 /*
2 * This program is a special utility for generating lists of ICCIDs
3 * following the 18+1 convention. The first argument is the starting
4 * ICCID without Luhn (entered as shorthand, expanded to 18 digits),
5 * the second argument is the number of consecutive ICCIDs to generate.
6 * The output is a list of full 19-digit ICCIDs.
